Canonical reference: FeatureValueGridDefinitionFactory.

Instructions

Add PositionColumn as the second column (after BulkActionColumn) in the Grid Definition.
Configure the position update route: ->setOption('update_method', 'POST')->setOption('update_route', 'admin_{domain}s_update_position').
Add a ReorderPositionsButtonType filter associated with the position column (see Rules below) — mandatory, not optional.
Create the admin_{domain}s_update_position POST route in the routing YAML (see create-admin-routing skill).
In the controller, handle the AJAX position update: receive positions[] array, dispatch UpdatePosition{Domain}Command (or use QueryBuilder directly).
In the repository, update the position column for the moved entities.

Rules

Column ordering conventions (PositionColumn as second column) are in Grid/CONTEXT.md. Skill-specific reminders:

Always pair the PositionColumn with a ReorderPositionsButtonType filter. It renders a "Rearrange" button (js-btn-reorder-positions) that toggles inline drag-and-drop mode — dramatically better UX than a numeric position search field. Use:
```
use PrestaShopBundle\Form\Admin\Type\ReorderPositionsButtonType;

->add((new Filter('position', ReorderPositionsButtonType::class))
    ->setAssociatedColumn('position')
);
```
Position updates are always AJAX — return JSON response, not redirect
Position values start at 0 or 1 — be consistent with existing PS convention
