init-grid-extensions

Development

Enable JavaScript grid extensions for a listing page. Extensions add sorting, filtering, bulk actions, column toggling, position reordering, and other interactive behaviors to the grid. Trigger: "add grid extensions for {Domain}", "enable grid extensions for {Domain}", "initialize grid JS for {Domain}".

init-grid-extensions

Read @.ai/Component/Javascript/CONTEXT.md for the grid component and extension system.

Basic pattern

In the listing entry point (index.ts):

const grid = new window.prestashop.component.Grid('{domain}');

grid.addExtension(new window.prestashop.component.GridExtensions.SortingExtension());
grid.addExtension(new window.prestashop.component.GridExtensions.FiltersResetExtension());
grid.addExtension(new window.prestashop.component.GridExtensions.SubmitRowActionExtension());
grid.addExtension(new window.prestashop.component.GridExtensions.SubmitBulkActionExtension());
grid.addExtension(new window.prestashop.component.GridExtensions.BulkActionCheckboxExtension());
grid.addExtension(new window.prestashop.component.GridExtensions.ColumnTogglingExtension());

The grid ID must match the GRID_ID const from the PHP grid definition factory.

Available extensions

Core extensions (most grids need these)

Extension	Purpose
`SortingExtension`	Clickable column headers for sorting
`FiltersResetExtension`	Reset button for grid filters
`FiltersSubmitButtonEnablerExtension`	Enable/disable filter submit button
`BulkActionCheckboxExtension`	Select-all and per-row checkboxes
`SubmitBulkActionExtension`	Submit bulk action form (enable/disable/delete)
`SubmitRowActionExtension`	Handle row action link clicks
`LinkRowActionExtension`	Navigate to row action URLs
`ColumnTogglingExtension`	Show/hide columns via dropdown

Specialized extensions (add only when needed)

Extension	Purpose	When to use
`AsyncToggleColumnExtension`	AJAX toggle for boolean columns	Entity has toggle status in grid
`PositionExtension`	Drag-and-drop row reordering	Entity has position column
`AjaxBulkActionExtension`	AJAX bulk actions (no page reload)	Performance-sensitive bulk ops
`ExportToSqlManagerExtension`	Export grid data to SQL manager	Grid needs SQL export
`ReloadListExtension`	Reload grid data without page refresh	AJAX-driven grid updates
`PreviewExtension`	Inline row preview expansion	Entity has preview/details panel
`ModalFormSubmitExtension`	Submit forms in modal dialogs	Delete confirmation modals
`BulkOpenTabsExtension`	Open multiple items in new tabs	Batch review workflows
`SubmitGridActionExtension`	Grid-level action buttons	Grid has toolbar actions (export, import)

Domain-specific extensions

Some domains have custom extensions in subdirectories:

column/catalog/ — catalog-specific column extensions
action/row/ — domain-specific row action extensions (e.g. customer delete with order check)

Check admin-dev/themes/new-theme/js/components/grid/extension/ for the full list.

Multiple grids on one page

For pages with multiple grids (e.g. Manufacturer with manufacturers + addresses):

const manufacturerGrid = new window.prestashop.component.Grid('manufacturer');
manufacturerGrid.addExtension(new SortingExtension());
// ...

const addressGrid = new window.prestashop.component.Grid('manufacturer_address');
addressGrid.addExtension(new SortingExtension());
// ...

Each grid instance gets its own set of extensions.

Rules

Conventions (multiple Grid instances pattern) are in Javascript/CONTEXT.md. Skill-specific reminders:

Grid ID must match the PHP GRID_ID constant — mismatch means extensions don't bind
Only add extensions that match the grid definition — don't add PositionExtension without a PositionColumn
AsyncToggleColumnExtension requires a matching AJAX toggle route in the controller
