Add navigation menu field type to Advanced Custom Fields

Alex Mills

<p>When adding a page, category, or any hierarchical custom post type or taxonomy to your navigation menu (Appearance → Menus), this plugin allows you to optionally automatically add all descendants (children) of that menu item as submenu items.</p>
<p>In short, you’ll no longer have to manually maintain submenus when you add a new child page to your site.</p>


Add Descendants As Submenu Items

Still works great. Much better than Gecka Submenu - it doesn't break the layout on the menu screen and there's no unnecessary pro version upsell.  I hope this is updated at some point because its age is hiding it from WP's search results.



Works great and it's clean

Automatically all of a nav menu item's descendants as submenu items. Designed for pages but will work with any hierarchical post type or taxonomy …
