How to add a custom metabox to the Menu Management admin screen?
In the backend of Wordpress, under Appearance -> Menus it allows you to add different post types by clicking on checkboxes and then "Add to Menu". Normally it will display Pages, Posts, and Custom Links - it will also display Custom Post types that are added.
Pages are based on hierarchy, however in the list they are not organized this way. This makes it difficult if you have many pages with the same name (that are common subpages of unique parents).
Is there anyway to modify this behaviour to add hierarchy to the listing? Is there a wordpress function that can be overwritten, or even a new module that can be added to support Page hierarchy in the Menu section?
