• Preserves menu item labels, targets, descriptions, CSS classes, and hierarchy

3. Menu Import Support

• Import navigation menus from theme settings export files

How to test the changes in this Pull Request:

Testing Custom Menus Page:

1. Navigate to Memberlite > Custom Menus in the WordPress admin.
2. Create a new menu by entering a name and clicking "Add Menu" - verify the menu is created.
3. Create another menu by selecting an existing menu from "Duplicate Items From" dropdown - verify menu items are copied with correct hierarchy.
4. Use the "Duplicate" button on an existing menu - verify a copy is created with "(Copy)" appended to the name.
5. Use the "Delete" button on a menu - verify confirmation dialog appears and menu is deleted.
6. Click "Edit" on a menu - verify it opens the WordPress menu editor.

Testing Menu Export:

1. Navigate to Memberlite > Tools.
2. In the Export Settings section, check "Include Navigation Menus" checkbox.
3. Select specific menus to export using the checkbox list.
4. Click "Download Export File" and verify the JSON file contains a menus array with menu data.
5. Verify menu item URLs that match the site URL are stored as relative paths (e.g., /about/ instead of https://example.com/about/).

Testing Menu Import:

1. Create an export file with menus from one site.
2. On another site (or after deleting the menus), navigate to Memberlite > Tools.
3. Upload the export file and import.
4. Verify menus are created with correct names (numbered if duplicates exist).
5. Verify menu items have correct labels, URLs (converted to absolute), and hierarchy.

Testing Cross-Environment Portability:

1. Export menus from a local development site.
2. Import on a staging or production site with a different URL.
3. Verify relative URLs are correctly converted to the new site's domain.

• Custom Menus Page ✅
• Menu Export ✅
• Menu Import ✅

Tested all the steps based on your instructions and it looks good. Nothing in the debug log. Only thing I didn't test was to import on a staging site with Memberlite. Otherwise, all good on my end. 👍
