Hello, @issy,
To enable categories, brands, and attributes in the WordPress menu editor, you can follow these steps:
1) Go to Appearance > Menus in your WordPress dashboard.
2) Click on the Screen Options button in the top-right corner of the screen.
3)In the Screen Options dropdown, check the boxes next to “Product Categories,” “Product Tags,” and “Product Attributes.”
4) Click the Screen Options button again to close the dropdown.
5) You should now see the new options for categories, tags, and attributes in the left-hand column of the menu editor.
6) To add a category, tag, or attribute to your menu, simply check the box next to the item you want to add and click the “Add to Menu” button.
By enabling these screen options, you should now be able to see and add categories, brands, and attributes directly from the WordPress menu editor without the need for any additional plugins or custom links.
