 Summary of the Issue
 In the Appearance > Menus screen, when adding WooCommerce Product
 Categories to a menu, the list of available categories under the "View
 All" tab is displayed as a flat, non-hierarchical list. Child categories
 are not indented or grouped under their parent categories. This forces
 users with many categories to search through multiple paginated pages to
 find and add related items, which is very inefficient.

 Steps to Reproduce
 Ensure you have WordPress and WooCommerce installed.

 Create a significant number of Product Categories with a clear parent-
 child structure. For example:

 Parent: لوازم بدنه (Body Parts)

 Children: شیشه جلو (Windshield), شیشه عقب (Rear Window), کاپوت (Hood),
 گلگیر (Fender).

 Create enough total categories to trigger pagination in the menu editor
 (typically more than 20).

 Navigate to Appearance > Menus.

 In the "Add menu items" panel on the left, expand the "Product categories"
 accordion.

 Click on the "View All" tab.

 Observe the list of categories.

 Expected Behavior
 Child categories should be listed directly underneath their respective
 parent category and should be visually indented to represent the
 hierarchy. For example:

 [ ] لوازم بدنه (Body Parts)

 [ ] شیشه جلو (Windshield)

 [ ] شیشه عقب (Rear Window)

 [ ] کاپوت (Hood)

 This allows for easy selection of related items without navigating away
 from the parent.

 Actual Behavior
 All product categories, both parent and child, are displayed in a single
 flat list, often sorted alphabetically or by ID. The hierarchical
 relationship is completely lost. Due to pagination, a child category can
 appear on a completely different page from its parent, making menu
 management extremely difficult for stores with large catalogs.

 The provided screenshot perfectly illustrates this problem, showing a flat
 list with pagination controls (1, 2, 3, ») at the top.
