We'll create fresh WordPress site with FB Page Attributes WP Menu installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Automatically keep the page parent structure from page attributes in sync with a menu. Once you select which menu you want to keep in sync, save a page parent, and menu will be automatically updated, or save the menu and the page parent will be automatically updated. You can also add a page to the menu straight from the page attributes area when editing a page.
