+# Testing Guide
+
+This project uses **Vitest** as the modern testing framework, replacing the previous Karma + Jasmine setup. Vitest provides faster test execution, better TypeScript support, and enhanced developer experience.
+
+## Quick Start
+
+```bash
+# Install dependencies
+yarn install
+
+# Run all tests once
+yarn test
+
+# Run tests in watch mode (development)
+yarn test:watch
+
+# Run tests with coverage
+yarn test:coverage
+
+# Open coverage report in browser  
+yarn test:coverage:html
+
+# Run tests with UI interface
+yarn test:ui
+```
+
+## Testing Framework
+
+### Vitest Features
+- ⚡ **Fast**: Native ESM support and Vite's dev server
+- 🔧 **Zero Config**: Works out of the box with TypeScript
+- 🎯 **Jest Compatible**: Same API as Jest for easy migration
+- 📊 **Built-in Coverage**: V8 coverage with multiple reporters
+- 🎨 **UI Interface**: Optional web UI for test debugging
+- 🔍 **Watch Mode**: Smart re-running of affected tests
+
+### Key Changes from Karma/Jasmine
+- `function() {}` → `() => {}` (arrow functions)
+- `jasmine.objectContaining()` → `expect.objectContaining()`
+- `toThrowError()` → `toThrow()`
+- Global `describe`, `it`, `expect` without imports
+
+## Test Scripts
+
+| Command | Description |
+|---------|-------------|
+| `yarn test` | Run tests once with linting |
+| `yarn test:watch` | Run tests in watch mode |
+| `yarn test:ui` | Open Vitest UI in browser |
+| `yarn test:coverage` | Run tests with coverage report |
+| `yarn test:coverage:ui` | Coverage with UI interface |
+| `yarn test:coverage:detailed` | Detailed coverage with thresholds |
+| `yarn test:coverage:html` | Generate and open HTML coverage |
+| `yarn test:coverage:lcov` | Generate LCOV format for CI |
+| `yarn test:ci` | CI-optimized run with JUnit output |
+
+## Coverage Reports
+
+### Coverage Thresholds
+- **Global**: 85% minimum for branches, functions, lines, statements
+- **Core Files**: 90% minimum for `gridstack.ts` and `gridstack-engine.ts`
+- **Utils**: 85% minimum for `utils.ts`
+
+### Coverage Formats
+- **HTML**: Interactive browser report at `coverage/index.html`
+- **LCOV**: For integration with CI tools and code coverage services
+- **JSON**: Machine-readable format for automated processing
+- **Text**: Terminal summary output
+- **JUnit**: XML format for CI/CD pipelines
+
+### Viewing Coverage
+```bash
+# Generate and view HTML coverage report
+yarn test:coverage:html
+
+# View coverage in terminal
+yarn test:coverage
+
+# Generate LCOV for external tools
+yarn test:coverage:lcov
+```
+
+## Configuration Files
+
+- **`vitest.config.ts`**: Main Vitest configuration
+- **`vitest.setup.ts`**: Test environment setup and global mocks
+- **`.vitestrc.coverage.ts`**: Enhanced coverage configuration
+- **`tsconfig.json`**: TypeScript configuration with Vitest types
+
+## Writing Tests
+
+### Basic Test Structure
+```typescript
+import { Utils } from '../src/utils';
+
+describe('Utils', () => {
+  it('should parse boolean values correctly', () => {
+    expect(Utils.toBool(true)).toBe(true);
+    expect(Utils.toBool(false)).toBe(false);
+    expect(Utils.toBool(1)).toBe(true);
+    expect(Utils.toBool(0)).toBe(false);
+  });
+});
+```
+
+### DOM Testing
+```typescript
+describe('GridStack DOM', () => {
+  beforeEach(() => {
+    document.body.innerHTML = '<div class="grid-stack"></div>';
+  });
+
+  it('should create grid element', () => {
+    const grid = document.querySelector('.grid-stack');
+    expect(grid).toBeInTheDocument();
+  });
+});
+```
+
+### Mocking
+```typescript
+// Mock a module
+vi.mock('../src/utils', () => ({
+  Utils: {
+    toBool: vi.fn()
+  }
+}));
+
+// Mock DOM APIs
+Object.defineProperty(window, 'ResizeObserver', {
+  value: vi.fn().mockImplementation(() => ({
+    observe: vi.fn(),
+    unobserve: vi.fn(),
+    disconnect: vi.fn()
+  }))
+});
+```
+
+## File Organization
+
+```
+spec/
+├── utils-spec.ts           # Utils module tests
+├── gridstack-spec.ts       # Main GridStack tests  
+├── gridstack-engine-spec.ts # Engine logic tests
+├── regression-spec.ts      # Regression tests
+└── e2e/                   # End-to-end tests (not in coverage)
+```
+
+## CI/CD Integration
+
+### GitHub Actions Example
+```yaml
+- name: Run Tests
+  run: yarn test:ci
+
+- name: Upload Coverage
+  uses: codecov/codecov-action@v3
+  with:
+    file: ./coverage/lcov.info
+```
+
+### Test Results
+- **JUnit XML**: `coverage/junit-report.xml`
+- **Coverage LCOV**: `coverage/lcov.info`
+- **Coverage JSON**: `coverage/coverage-final.json`
+
+## Debugging Tests
+
+### VS Code Integration
+1. Install "Vitest" extension
+2. Run tests directly from editor
+3. Set breakpoints and debug
+
+### Browser UI
+```bash
+yarn test:ui
+```
+Opens a web interface for:
+- Running individual tests
+- Viewing test results
+- Coverage visualization
+- Real-time updates
+
+## Performance
+
+### Speed Comparison
+- **Karma + Jasmine**: ~15-20 seconds
+- **Vitest**: ~3-5 seconds
+- **Watch Mode**: Sub-second re-runs
+
+### Optimization Tips
+- Use `vi.mock()` for heavy dependencies
+- Prefer `toBe()` over `toEqual()` for primitives
+- Group related tests in `describe` blocks
+- Use `beforeEach`/`afterEach` for setup/cleanup
+
+## Migration Notes
+
+This project was migrated from Karma + Jasmine to Vitest with the following changes:
+
+1. **Dependencies**: Removed karma-\* packages, added vitest + utilities
+2. **Configuration**: Replaced `karma.conf.js` with `vitest.config.ts`
+3. **Syntax**: Updated test syntax to modern ES6+ style
+4. **Coverage**: Enhanced coverage with V8 provider and multiple formats
+5. **Scripts**: New npm scripts for various testing workflows
+
+All existing tests were preserved and converted to work with Vitest.

+
+can be used when a new item needs to be created, which we do as a Angular component, or deleted (skip)
+
+#### Parameters
+
+| Parameter | Type |
+| ------ | ------ |
+| `host` | `HTMLElement` \| [`GridCompHTMLElement`](#gridcomphtmlelement) |
+| `n` | [`NgGridStackNode`](types.md#nggridstacknode) |

+
+called for each item in the grid - check if additional information needs to be saved.
+Note: since this is options minus gridstack protected members using Utils.removeInternalForSave(),
+this typically doesn't need to do anything. However your custom Component @Input() are now supported
+using BaseWidget.serialize()
+
+#### Parameters

+
+#### Deprecated
+
+Use GridstackComponent and GridstackItemComponent as standalone components instead.
+
+This NgModule is provided for backward compatibility but is no longer the recommended approach.
+Import components directly in your standalone components or use the new Angular module structure.
+
+#### Example
+
+```typescript
+// Preferred approach - standalone components
+@Component({
+  selector: 'my-app',
+  imports: [GridstackComponent, GridstackItemComponent],
+  template: '<gridstack></gridstack>'
+})

+### GridStack
+
+Defined in: [gridstack.ts:76](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L76)
+
+Main gridstack class - you will need to call `GridStack.init()` first to initialize your grid.
+Note: your grid elements MUST have the following classes for the CSS layout to work:
+
+#### Example
+
+```ts
+<div class="grid-stack">
+  <div class="grid-stack-item">
+    <div class="grid-stack-item-content">Item 1</div>
+  </div>
+</div>
+```
+
+#### Constructors
+
+##### Constructor
+
+```ts
+new GridStack(el, opts): GridStack;
+```
+
+Defined in: [gridstack.ts:266](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L266)
+
+Construct a grid item from the given element and options
+
+###### Parameters
+
+| Parameter | Type | Description |
+| ------ | ------ | ------ |
+| `el` | [`GridHTMLElement`](#gridhtmlelement) | the HTML element tied to this grid after it's been initialized |
+| `opts` | [`GridStackOptions`](#gridstackoptions) | grid options - public for classes to access, but use methods to modify! |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+
+#### Methods
+
+##### \_updateResizeEvent()
+
+```ts
+protected _updateResizeEvent(forceRemove): GridStack;
+```
+
+Defined in: [gridstack.ts:2091](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L2091)
+
+add or remove the grid element size event handler
+
+###### Parameters
+
+| Parameter | Type | Default value |
+| ------ | ------ | ------ |
+| `forceRemove` | `boolean` | `false` |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+
+##### \_widthOrContainer()
+
+```ts
+protected _widthOrContainer(forBreakpoint): number;
+```
+
+Defined in: [gridstack.ts:954](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L954)
+
+return our expected width (or parent) , and optionally of window for dynamic column check
+
+###### Parameters
+
+| Parameter | Type | Default value |
+| ------ | ------ | ------ |
+| `forBreakpoint` | `boolean` | `false` |
+
+###### Returns
+
+`number`
+
+##### addGrid()
+
+```ts
+static addGrid(parent, opt): GridStack;
+```
+
+Defined in: [gridstack.ts:141](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L141)
+
+call to create a grid with the given options, including loading any children from JSON structure. This will call GridStack.init(), then
+grid.load() on any passed children (recursively). Great alternative to calling init() if you want entire grid to come from
+JSON serialized data, including options.
+
+###### Parameters
+
+| Parameter | Type | Description |
+| ------ | ------ | ------ |
+| `parent` | `HTMLElement` | HTML element parent to the grid |
+| `opt` | [`GridStackOptions`](#gridstackoptions) | grids options used to initialize the grid, and list of children |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+
+##### addWidget()
+
+```ts
+addWidget(w): GridItemHTMLElement;
+```
+
+Defined in: [gridstack.ts:432](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L432)
+
+add a new widget and returns it.
+
+Widget will be always placed even if result height is more than actual grid height.
+You need to use `willItFit()` before calling addWidget for additional check.
+See also `makeWidget(el)` for DOM element.
+
+###### Parameters
+
+| Parameter | Type | Description |
+| ------ | ------ | ------ |
+| `w` | [`GridStackWidget`](#gridstackwidget) | GridStackWidget definition. used MakeWidget(el) if you have dom element instead. |
+
+###### Returns
+
+[`GridItemHTMLElement`](#griditemhtmlelement)
+
+###### Example
+
+```ts
+const grid = GridStack.init();
+grid.addWidget({w: 3, content: 'hello'});
+```
+
+##### batchUpdate()
+
+```ts
+batchUpdate(flag): GridStack;
+```
+
+Defined in: [gridstack.ts:833](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L833)
+
+use before calling a bunch of `addWidget()` to prevent un-necessary relayouts in between (more efficient)
+and get a single event callback. You will see no changes until `batchUpdate(false)` is called.
+
+###### Parameters
+
+| Parameter | Type | Default value |
+| ------ | ------ | ------ |
+| `flag` | `boolean` | `true` |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+
+##### cellHeight()
+
+```ts
+cellHeight(val?): GridStack;
+```
+
+Defined in: [gridstack.ts:904](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L904)
+
+Update current cell height - see `GridStackOptions.cellHeight` for format by updating eh Browser CSS variable.
+
+###### Parameters
+
+| Parameter | Type | Description |
+| ------ | ------ | ------ |
+| `val?` | [`numberOrString`](#numberorstring) | the cell height. Options: - `undefined`: cells content will be made square (match width minus margin) - `0`: the CSS will be generated by the application instead - number: height in pixels - string: height with units (e.g., '70px', '5rem', '2em') |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+
+the grid instance for chaining
+
+###### Example
+
+```ts
+grid.cellHeight(100);     // 100px height
+grid.cellHeight('70px');  // explicit pixel height
+grid.cellHeight('5rem');  // relative to root font size
+grid.cellHeight(grid.cellWidth() * 1.2); // aspect ratio
+grid.cellHeight('auto');  // auto-size based on content
+```
+
+##### cellWidth()
+
+```ts
+cellWidth(): number;
+```
+
+Defined in: [gridstack.ts:950](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L950)
+
+Gets the current cell width in pixels. This is calculated based on the grid container width divided by the number of columns.
+
+###### Returns
+
+`number`
+
+the cell width in pixels
+
+###### Example
+
+```ts
+const width = grid.cellWidth();
+console.log('Cell width:', width, 'px');
+
+// Use cell width to calculate widget dimensions
+const widgetWidth = width * 3; // For a 3-column wide widget
+```
+
+##### checkDynamicColumn()
+
+```ts
+protected checkDynamicColumn(): boolean;
+```
+
+Defined in: [gridstack.ts:960](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L960)
+
+checks for dynamic column count for our current size, returning true if changed
+
+###### Returns
+
+`boolean`
+
+##### column()
+
+```ts
+column(column, layout): GridStack;
+```
+
+Defined in: [gridstack.ts:1039](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack.ts#L1039)
+
+Set the number of columns in the grid. Will update existing widgets to conform to new number of columns,
+as well as cache the original layout so you can revert back to previous positions without loss.
+
+Requires `gridstack-extra.css` or `gridstack-extra.min.css` for [2-11] columns,
+else you will need to generate correct CSS.
+See: https://github.com/gridstack/gridstack.js#change-grid-columns
+
+###### Parameters
+
+| Parameter | Type | Default value | Description |
+| ------ | ------ | ------ | ------ |
+| `column` | `number` | `undefined` | Integer > 0 (default 12) |
+| `layout` | [`ColumnOptions`](#columnoptions) | `'moveScale'` | specify the type of re-layout that will happen. Options: - 'moveScale' (default): scale widget positions and sizes - 'move': keep widget sizes, only move positions - 'scale': keep widget positions, only scale sizes - 'none': don't change widget positions or sizes Note: items will never be outside of the current column boundaries. Ignored for `column=1` as we always want to vertically stack. |
+
+###### Returns
+
+[`GridStack`](#gridstack-1)
+

+
+| Parameter | Type | Default value | Description |
+| ------ | ------ | ------ | ------ |
+| `saveContent` | `boolean` | `true` | if true (default) the latest html inside .grid-stack-content will be saved to GridStackWidget.content field, else it will be removed. |
+| `saveGridOpt` | `boolean` | `false` | if true (default false), save the grid options itself, so you can call the new GridStack.addGrid() to recreate everything from scratch. GridStackOptions.children would then contain the widget list instead. |
+| `saveCB` | [`SaveFcn`](#savefcn) | `GridStack.saveCB` | callback for each node -> widget, so application can insert additional data to be saved into the widget data structure. |
+| `column?` | `number` | `undefined` | if provided, the grid will be saved for the given column size (IFF we have matching internal saved layout, or current layout). Otherwise it will use the largest possible layout (say 12 even if rendering at 1 column) so we can restore to all layouts. NOTE: if you want to save to currently display layout, pass this.getColumn() as column. NOTE2: nested grids will ALWAYS save to the container size to be in sync with parent. |

+### GridStackEngine
+
+Defined in: [gridstack-engine.ts:34](https://github.com/adumesny/gridstack.js/blob/master/src/gridstack-engine.ts#L34)
+
+Defines the GridStack engine that handles all grid layout calculations and node positioning.
+This is the core engine that performs grid manipulation without any DOM operations.
+
+The engine manages:
+- Node positioning and collision detection
+- Layout algorithms (compact, float, etc.)
+- Grid resizing and column changes
+- Widget movement and resizing logic
+
+NOTE: Values should not be modified directly - use the main GridStack API instead
+to ensure proper DOM updates and event triggers.
+

-## Grid Options
-
-- `acceptWidgets` - Accept widgets dragged from other grids or from outside (default: `false`). Can be:
-   * `true` will accept HTML element having `'grid-stack-item'` as class attribute, else `false`
-   * string for explicit class name to accept instead
-   * `function (el: Element): boolean` function called before an item will be accepted when entering a grid. the function will be passed the item being dragged, and should return true | false. See [example](https://github.com/gridstack/gridstack.js/blob/master/demo/two.html#L62)
-- `alwaysShowResizeHandle` - possible values (default: `mobile`) - does not apply to non-resizable widgets
-  * `false` the resizing handles are only shown while hovering over a widget
-  * `true` the resizing handles are always shown
-  * `'mobile'` if running on a mobile device, default to `true` (since there is no hovering per say), else `false`.
-  See [mobile](http://gridstack.github.io/gridstack.js/demo/mobile.html)
-
-
-- `animate` - turns animation on to smooth transitions (default: `true`)
-- `auto` - if `false` gridstack will not initialize existing items (default: `true`)
-- `cellHeight`- one cell height (default?: 'auto'). Can be:
-   *  an integer (px)
-   *  a string (ex: '100px', '10em', '10rem', '10cm'). Note: % doesn't right - see [CellHeight](http://gridstackjs.com/demo/cell-height.html)
-   *  0, in which case the library will not generate styles for rows. Everything must be defined in your own CSS files.
-   *  `auto` - height will be calculated for square cells (width / column) and updated live as you resize the window - also see `cellHeightThrottle`
-   *  `initial` - similar to 'auto' (start at square cells) but stay that size during window resizing.
-- `cellHeightThrottle`?: number - throttle time delay (in ms) used when cellHeight='auto' to improve performance vs usability (default?: 100).
-   * A value of 0 will make it instant at a cost of re-creating the CSS file at ever window resize event!
-- `children`?: GridStackWidget[] - list of children item to create when calling load() or addGrid()
-- `column` - Integer > 0 (default 12) which can change on the fly with `column(N)` API, or `'auto'` for nested grids to size themselves to the parent grid container (to make sub-items are the same size). See [column](http://gridstackjs.com/demo/column.html) and [nested](http://gridstackjs.com/demo/nested.html)
-- `columnOpts`?:Responsive - describes the responsive nature of the column grid. see `Responsive` interface.
-- `class`?: string - additional class on top of '.grid-stack' (which is required for our CSS) to differentiate this instance
-- `disableDrag` - disallows dragging of widgets (default: `false`).
-- `disableResize` - disallows resizing of widgets (default: `false`).
-- `draggable` - allows to override draggable options - see `DDDragOpt`. (default: `{handle: '.grid-stack-item-content', appendTo: 'body', scroll: true}`)
-- `engineClass` - the type of engine to create (so you can subclass) default to GridStackEngine
-- `sizeToContent`: boolean - make gridItems size themselves to their content, calling `resizeToContent(el)` whenever the grid or item is resized.
-- `float` - enable floating widgets (default: `false`) See [example](http://gridstackjs.com/demo/float.html)
-- `handle` - draggable handle selector (default: `'.grid-stack-item-content'`)
-- `handleClass` - draggable handle class (e.g. `'grid-stack-item-content'`). If set `handle` is ignored (default: `null`)
-- `itemClass` - widget class (default: `'grid-stack-item'`)
-- `lazyLoad?`: boolean - true when widgets are only created when they scroll into view (visible). also overridable per widget in `GridStackWidget`
-- `margin` - gap size around grid item and content (default: `10`). Can be:
-  * an integer (px)
-  * a string (ex: '2em', '20px', '2rem')
-- `marginTop`: numberOrString - can set individual settings (defaults to `margin`)
-- `marginRight`: numberOrString
-- `marginBottom`: numberOrString
-- `marginLeft`: numberOrString
-- `maxRow` - maximum rows amount. Default is `0` which means no max.
-- `minRow` - minimum rows amount which is handy to prevent grid from collapsing when empty. Default is `0`. You can also do this with `min-height` CSS attribute on the grid div in pixels, which will round to the closest row.
-- `nonce` - If you are using a nonce-based Content Security Policy, pass your nonce here and
-GridStack will add it to the `<style>` elements it creates.
-- `placeholderClass` - class for placeholder (default: `'grid-stack-placeholder'`)
-- `placeholderText` - placeholder default content (default: `''`)
-- `resizable` - allows to override resizable options. (default: `{handles: 'se'}`). `handles` can be any combo of `n,ne,e,se,s,sw,w,nw` or `all`.
-- `removable` - if `true` widgets could be removed by dragging outside of the grid. It could also be a selector string, in this case widgets will be removed by dropping them there (default: `false`) See [example](http://gridstackjs.com/demo/two.html)
-- `removeTimeout` - time in milliseconds before widget is being removed while dragging outside of the grid. (default: `2000`)
-- `row` - fix grid number of rows. This is a shortcut of writing `minRow:N, maxRow:N`. (default `0` no constrain)
-- `rtl` - if `true` turns grid to RTL. Possible values are `true`, `false`, `'auto'` (default: `'auto'`) See [example](https://gridstackjs.com/demo/right-to-left(rtl).html)
-- `staticGrid` - removes drag|drop|resize (default `false`). If `true` widgets are not movable/resizable by the user, but code can still move and oneColumnMode will still work. You can use the smaller gridstack-static.js lib. A CSS class `grid-stack-static` is also added to the container.
-
-### Responsive
-v10.x supports a much richer responsive behavior, you can have breakpoints of width:column, or auto column sizing,  where no code is longer needed.
-- `columnWidth`?: number - wanted width to maintain (+-50%) to dynamically pick a column count
-- `columnMax`?: number - maximum number of columns allowed (default: 12). Note: make sure to have correct CSS to support this.
-- `layout`?: ColumnOptions - global re-layout mode when changing columns
-- `breakpointForWindow`?: boolean - specify if breakpoints are for window size or grid size (default:false = grid)
-- `breakpoints`?: Breakpoint[] - explicit width:column breakpoints instead of automatic 'columnWidth'. Note: make sure to have correct CSS to support this.
-
-#### Breakpoint
-- `w`?: number - width
-- `c`: number - column
-- `layout`?: ColumnOptions - re-layout mode if different from global one
-
-### DDDragOpt
-- `handle`?: string - class selector of items that can be dragged. default to '.grid-stack-item-content'
-- `appendTo`?: string - default to 'body' (TODO: is this even used anymore ?)
-- `pause`?: boolean | number - if set (true | msec), dragging placement (collision) will only happen after a pause by the user. Note: this is Global
-- `scroll`?: boolean - default to 'true', enable or disable the scroll when an element is dragged on bottom or top of the grid.
-- `cancel`?: string - prevents dragging from starting on specified elements, listed as comma separated selectors (eg: '.no-drag'). default built in is 'input,textarea,button,select,option'
-- `helper`?: 'clone' | ((el: HTMLElement) => HTMLElement) - helper function when dragging side panel items that need to be cloned before dropping (ex: 'clone' or your own method)
-
-## Grid attributes
-
-most of the above options are also available as HTML attributes using the `gs-` name prefix with standard dash lower case naming convention (ex: `gs-column`, `gs-min-row`, `gs-static`, etc..).
-
-Extras:
-- `gs-current-row` - (internal) current rows amount. Set by the library only. Can be used by the CSS rules.
-
-## Item Options - GridStackWidget
-
-options you can pass when calling `addWidget()`, `update()`, `load()` and many others
-
-- `autoPosition` - tells to ignore `x` and `y` attributes and to place element to the first available position. Having either one missing will also do that.
-- `x`, `y` - (number) element position in column/row. Note: if one is missing this will `autoPosition` the item
-- `w`, `h` - (number) element size in column/row (default 1x1)
-- `maxW`, `minW`, `maxH`, `minH` - element constraints in column/row (default none)
-- `locked` - means another widget wouldn't be able to move it during dragging or resizing.
-The widget can still be dragged or resized by the user.
-You need to add `noResize` and `noMove` attributes to completely lock the widget.
-- `noResize` - disable element resizing
-- `noMove` - disable element moving
-- `id`- (number | string) good for quick identification (for example in change event)
-- `content` - (string) html content to be added when calling `grid.load()/addWidget()` as content inside the item
-- `sizeToContent`?: boolean | number - make gridItem size itself to the content, calling `GridStack.resizeToContent(el)` whenever the grid or item is resized.
-Note: This also allow you to set a maximum h value (but user changeable during normal resizing) to prevent unlimited content from taking too much space (get scrollbar)
-- `subGrid`?: GridStackOptions - optional nested grid options and list of children
-- `subGridDynamic`?: boolean - enable/disable the creation of sub-grids on the fly by dragging items completely over others (nest) vs partially (push). Forces `DDDragOpt.pause=true` to accomplish that.
-- `lazyLoad?`: boolean - true when widgets are only created when they scroll into view (visible). also optin on entire grid.
-
-## Item attributes
-
-all item options are also available as HTML attributes using the `gs-` name prefix with standard dash lower case naming convention (ex: `gs-x`, `gs-min-w`, etc..).
-
-## Events
-
-Those are events generated by the grid when items are added/removed/changed or drag&drop interaction. In general they pass list of nodes that changed (id, x, y, width, height, etc...) or individual DOM element
-that is affected.
-
-You can call it on a single event name, or space separated list like:
-`grid.on('added removed change', ...)`
-
-The Typescript `GridStackEvent` list all possible values, and nothing else is supported by the `grid.on()` method, though it's possible to register directly for other events generated by the drag&drop plugging implementation detail (if jquery-ui based you can still use `$(".grid-stack").on(...)`).

-});
-```
-
-### prepareDragDrop(el: GridItemHTMLElement, force = false) : GridStack
-prepares the element for drag&drop - this is normally called by makeWiget() unless are are delay loading
-* @param el GridItemHTMLElement of the widget
-* @param [force=false] 
-
-
-## API Global (static)
-
-### `init(options: GridStackOptions = {}, elOrString: GridStackElement = '.grid-stack'): GridStack`
-
-* initializing the HTML element, or selector string, into a grid will return the grid. Calling it again will
-simply return the existing instance (ignore any passed options). There is also an initAll() version that support multiple grids initialization at once. Or you can use addGrid() to create the entire grid from JSON.
-* @param options grid options (optional)
-* @param elOrString element or CSS selector (first one used) to convert to a grid (default to `'.grid-stack'` class selector)
-```js
-let grid = GridStack.init();
-// Note: the HTMLElement (of type GridHTMLElement) will store a `gridstack: GridStack` value that can be retrieve later
-let grid = document.querySelector('.grid-stack').gridstack;
-```
-
-### `initAll(options: GridStackOptions = {}, selector = '.grid-stack'): GridStack[]`
-
-* Will initialize a list of elements (given a selector) and return an array of grids.
-* @param options grid options (optional)
-* @param selector elements selector to convert to grids (default to '.grid-stack' class selector)
-
-```js
-let grids = GridStack.initAll();
-grids.forEach(...)
-```
-
-### `addGrid(parent: HTMLElement, opt: GridStackOptions = {}): GridStack `
-
-* call to create a grid with the given options, including loading any children from JSON structure. This will call `GridStack.init()`, then `grid.load()` on any passed children (recursively). Great alternative to calling `init()` if you want entire grid to come from JSON serialized data, including options.
-* @param parent HTML element parent to the grid
-* @param opt grids options used to initialize the grid, and list of children
-* see [nested.html](https://github.com/gridstack/gridstack.js/tree/master/demo/nested.html) demo
-
-### `setupDragIn(dragIn?: string | HTMLElement[], dragInOptions?: DDDragOpt, widgets?: GridStackWidget[], root = HTMLElement | Document)`
-
-* call to setup dragging in from the outside (say toolbar), by specifying the class selection and options.
-Called during `GridStack.init()` as options, but can also be called directly (last param are cached) in case the toolbar is dynamically create and needs to change later.
-* @param `dragIn` string selector (ex: `'.sidebar-item'`) or list of dom elements
-* @param `dragInOptions` options - see `DDDragOpt`. default: `{appendTo: 'body', helper: 'clone'}`
-* @param `widgets` GridStackWidget def to assign to each element which defines what to create on drop
-Note: you can instead use DOM attr `data-gs-widget` for complete JSON string of that GridStackWidget.
-* @param `root` optional root which defaults to document (for shadow dom pass the parent HTMLDocument)
-
-### `GridStack.registerEngine(engineClass: typeof GridStackEngine)`
-
-* call to specify global custom engine subclass - see instead `GridStackOptions.engineClass` if you only need to replace just one instance.
-## API
-
-### `addWidget(w: GridStackWidget): GridItemHTMLElement`
-
-Creates new widget and returns it.
-
-Parameters:
-
-- `w`: GridStackWidget - widget position/size options - see GridStackWidget
-
-Widget will be always placed even if result height is more than actual grid height. You need to use `willItFit` method
-before calling `addWidget` for additional check.
-
-```js
-let grid = GridStack.init();
-grid.addWidget({w: 3, content: 'hello'});
-```
-
-### `batchUpdate(flag = true)`
-
-use before calling a bunch of `addWidget()` to prevent un-necessary relayouts in between (more efficient) and get a single event callback. You will see no changes until `batchUpdate(false)` is called.
-
-### `compact(layout: CompactOptions = 'compact', doSort = true)`
-
-re-layout grid items to reclaim any empty space. Options are:
-- `'list'` keep the widget left->right order the same, even if that means leaving an empty slot if things don't fit
-- `'compact'` might re-order items to fill any empty space
-
-- `doSort` - `false` to let you do your own sorting ahead in case you need to control a different order. (default to sort)
-
-
-### `cellHeight(val: number, update = true)`
-
-Update current cell height (see - `cellHeight` options format). This method rebuilds an internal CSS stylesheet (unless optional update=false). Note: You can expect performance issues if call this method too often.
-
-```js
-grid.cellHeight(grid.cellWidth() * 1.2);
-```
-
-### `cellWidth()`
-
-Gets current cell width (grid width / # of columns).
-
-### `column(column: number, layout: ColumnOptions = 'moveScale')`
-
-set the number of columns in the grid. Will update existing widgets to conform to new number of columns,
-as well as cache the original layout so you can revert back to previous positions without loss.
-Requires `gridstack-extra.css` (or minimized version) for [2-11],
-else you will need to generate correct CSS (see https://github.com/gridstack/gridstack.js#change-grid-columns)
-
-- `column` - Integer > 0 (default 12)
-- `layout` - specify the type of re-layout that will happen (position, size, etc...). Values are: `'list' | 'compact' | 'moveScale' | 'move' | 'scale' | 'none' | ((column: number, oldColumn: number, nodes: GridStackNode[], oldNodes: GridStackNode[]) => void);`
-
-* `'list'` - treat items as sorted list, keeping items (un-sized unless too big for column count) sequentially reflowing them
-* `'compact'` - similar to list, but using compact() method which will possibly re-order items if an empty slots are available due to a larger item needing to be pushed to next row
-* `'moveScale'` - will scale and move items by the ratio new newColumnCount / oldColumnCount
-* `'move'` | `'scale'` - will only size or move items
-* `'none'` will leave items unchanged, unless they don't fit in column count
-* custom function that takes new/old column count, and array of new/old positions
-Note: new list may be partially already filled if we have a partial cache of the layout at that size (items were added later). If complete cache is present this won't get called at all.
-
-### `destroy([removeDOM])`
-
-Destroys a grid instance.
-
-Parameters:
-
-- `removeDOM` - if `false` nodes and grid will not be removed from the DOM (Optional. Default `true`).
-
-### `disable()`
-
-Disables widgets moving/resizing. This is a shortcut for:
-
-```js
-grid.enableMove(false);
-grid.enableResize(false);
-```
-
-### `enable()`
-
-Enables widgets moving/resizing. This is a shortcut for:
-
-```js
-grid.enableMove(true);
-grid.enableResize(true);
-```
-
-### `enableMove(doEnable)`
-
-Enables/disables widget moving (default: true), and setting the `disableDrag` grid option. This is a shortcut for:
-
-```js
-grid.opts.disableDrag = !doEnable;
-grid.movable('.grid-stack-item', doEnable);
-```
-
-### `enableResize(doEnable)`
-
-Enables/disables widget sizing (default: true), and setting the `disableResize` grid option. This is a shortcut for:
-
-```js
-grid.opts.disableResize = !doEnable;
-grid.resizable('.grid-stack-item', doEnable);
-```
-
-### `float(val?)`
-
-set/get floating widgets (default: `false`)
-
-- `val` - boolean to set true/false, else get the current value
-
-### `getCellHeight()`
-
-Gets current cell height.
-
-
-### `getCellFromPixel(position[, useOffset])`
-
-Get the position of the cell under a pixel on screen.
-
-Parameters :
-
-- `position` - the position of the pixel to resolve in absolute coordinates, as an object with `top` and `left` properties
-- `useOffset` - if `true`, value will be based on offset vs position (Optional. Default `false`). Useful when grid is within `position: relative` element.
-
-Returns an object with properties `x` and `y` i.e. the column and row in the grid.
-
-### `getColumn(): number`
-
-returns the number of columns in the grid.
-
-### `getGridItems(): GridItemHTMLElement[]`
-
-Return list of GridItem HTML elements (excluding temporary placeholder) in DOM order, wether they are node items yet or not (looks by class)
-
-### `getMargin()`
-
-returns current margin value (undefined if all 4 sides don't match).
-
-### `isAreaEmpty(x, y, width, height)`
-
-Checks if specified area is empty.
-
-### `load(items: GridStackWidget[], addRemove: boolean | AddRemoveFcn = GridStack.addRemoveCB || true)`
-
-- load the widgets from a list (see `save()`). This will call `update()` on each (matching by id) or add/remove widgets that are not there.
-- Optional `addRemove` boolean (default true) or callback method can be passed to control if and how missing widgets can be added/removed, giving the user control of insertion.
-
-- used to restore a grid layout for a saved layout list (see `save()`).
-- `addRemove` boolean (default true) or callback method can be passed to control if and how missing widgets can be added/removed, giving the user control of insertion.
-- see [example](http://gridstackjs.com/demo/serialization.html)
-
-### `makeWidget(el)`
-
-If you add elements to your gridstack container by hand, you have to tell gridstack afterwards to make them widgets. If you want gridstack to add the elements for you, use `addWidget` instead.
-Makes the given element a widget and returns it.
-
-Parameters:
-
-- `el` - element to convert to a widget
-
-```js
-let grid = GridStack.init();
-// ...create some html content, possibly looking like: 
-// <div id="item-1" gs-x="0" gs-y="0" gs-w="3" gs-h="2"></div>'
-grid.makeWidget('#item-1');
-```
-### `makeSubGrid(el)`
-Used to add a subgrid into an existing grid.
-```js
-const grid = Gridstack.init()
-// ...create some html content, possibly looking like: 
-// <div id="gsi-1" gs-x="0" gs-y="0" gs-w="3" gs-h="2">
-//  <div class="grid-stack" id="nested-grid">
-//    <div id="gsi-2" gs-w="3" gs-h="2"></div>
-//  </div>
-//</div>
-grid.makeSubGrid(grid.el.getElementById('nested-grid'))
-```
-Make sure that the subgrid is inside of a grid item. It is important to remember that subgrids are themselves grid items capable of containing other grid items.
-### `margin(value: numberOrString)`
-
-gap between grid item and content (default?: 10). This will set all 4 sides and support the CSS formats below
- - an `integer` (px)
- - a string with possible units (ex: `'5'`, `'2em'`, `'20px'`, `'2rem'`)
- - string with space separated values (ex: `'5px 10px 0 20px'` for all 4 sides, or `'5em 10em'` for top/bottom and left/right pairs like CSS).
- - Note: all sides must have same units (last one wins, default px)
-
-### `movable(el, val)`
-
-Enables/Disables dragging by the user of specific grid element. If you want all items, and have it affect future items, use enableMove() instead. No-op for static grids.
-IF you are looking to prevent an item from moving (due to being pushed around by another during collision) use locked property instead.
-
-- `el` - widget to modify
-- `val` - if `true` widget will be draggable.
-
-### `removeWidget(el, removeDOM = true, triggerEvent = true)`
-
-Removes widget from the grid.
-
-Parameters:
-
-- `el` - widget to remove.
-- `removeDOM` - if `false` node won't be removed from the DOM (Optional. Default `true`).
-- `triggerEvent` if `false` (quiet mode) element will not be added to removed list and no 'removed' callbacks will be called (Default `true`).
-
-### `removeAll(removeDOM = true)`
-
-Removes all widgets from the grid.
-
-Parameters:
-
-- `removeDOM` - if `false` nodes won't be removed from the DOM (Optional. Default `true`).
-
-### `resizable(el, val)`
-
-Enables/Disables user resizing of specific grid element. If you want all items, and have it affect future items, use enableResize() instead. No-op for static grids.
-
-- `el` - widget to modify
-- `val` - if `true` widget will be resizable.
-
-### `resizeToContent(el: GridItemHTMLElement, useAttrSize = false)`
-
-Updates widget height to match the content height to avoid v-scrollbar or dead space.
-Note: this assumes only 1 child under `resizeToContentParent='.grid-stack-item-content'` (sized to gridItem minus padding) that is at the entire content size wanted.
-- `useAttrSize` set to `true` if GridStackNode.h should be used instead of actual container height when we don't need to wait for animation to finish to get actual DOM heights
-
-### `rotate(els: GridStackElement, relative?: Position)`
-rotate (by swapping w & h) the passed in node - called when user press 'r' during dragging
-
-- `els` - widget or selector of objects to modify
-- `relative` - optional pixel coord relative to upper/left corner to rotate around (will keep that cell under cursor)
-
-### `save(saveContent = true, saveGridOpt = false): GridStackWidget[] | GridStackOptions`
-
-saves the current layout returning a list of widgets for serialization which might include any nested grids.
-- `saveContent` if true (default) the latest html inside `.grid-stack-content` will be saved to `GridStackWidget.content` field, else it will be removed.
-- `saveGridOpt` if true (default `false`), save the grid options itself, so you can call the new `GridStack.addGrid()` to recreate everything from scratch. GridStackOptions.children would then contain the widget list instead.
-- returns list of widgets or full grid option, including .children list of widgets
-- see [serialization](http://gridstackjs.com/demo/serialization.html) and [nested](http://gridstackjs.com/demo/nested.html)
-
-### `setAnimation(doAnimate)`
-
-Toggle the grid animation state.  Toggles the `grid-stack-animate` class.
-
-- `doAnimate` - if `true` the grid will animate.
-
-### `setStatic(staticValue)`
-
-Toggle the grid static state.  Also toggle the `grid-stack-static` class.
-
-- `staticValue` - if `true` the grid becomes static.
-
-### `update(el: GridStackElement, opts: GridStackWidget)`
-
-Parameters:
-
-- `el` - widget to move (element or class string)
-- `opts` - updates all the possible item attributes passed in the structure (x, y, h, w, etc..). Only those set will be updated.
-
-Updates widget position/size and other info. Note: if you need to call this on all nodes, use load() instead which will update what changed and more.
-
-### `willItFit(x, y, width, height, autoPosition)`
-
-Returns `true` if the `height` of the grid will be less the vertical constraint. Always returns `true` if grid doesn't
-have `height` constraint.
-
-```js
-if (grid.willItFit(newNode.x, newNode.y, newNode.w, newNode.h, newNode.autoPosition)) {
-  grid.addWidget(newNode.el, newNode);
-}
-else {
-  alert('Not enough free space to place the widget');
-}
-```
-
-## Utils
-
-### `GridStack.Utils.sort(nodes[, dir])`
-
-Sorts array of nodes
-
-- `nodes` - array to sort
-- `dir` - `1` for ascending, `-1` for descending (optional)
