The New Nine Menus Manager adds a section to the ‘Appearance -> Menus’ section of your dashboard so you can quickly and easily create and delete menu locations on the fly.
Why? Because we’re tired of jumping back and forth between our functions file and the dashboard. Because we’re tired of writing <code>register_nav_menu</code> over and over again every time we start a new site.
And because there seems to be a disconnect here – just about every site needs to have a navigation menu, there are no configuration options for <code>register_nav_menu</code>, and it just seems to make sense to be able to create and delete menu locations in the dashboard.

Add pages, posts, or any other custom post types to any of your registered WordPress menus directly from the post editor page. Check the checkbox for the menu to add a the post / page / custom post type to, update the post / page / custom post type and it will then be added to the top level of all the checked menus.
You can control which post types display the ‘Add to Menu’ meta box by going to the ‘Settings > Post to Menu’ page.
If the post type has hierarchal structure (such as parent Pages), this will try to place the new menu item underneath a menu item that links to an ancestor post (if menu item exists).

Post to Menu
