I have a site. it contains a few navigation menus that i've registered with the function "register_nav_menus()".
Now, all of these menus have been listed inside "theme location" meta box in "menus" admin page.
I want to sort and categorize listed menus inside multiple meta boxes.
nav menu 1
nav menu 2
nav menu 3
nav menu 4
How can i do this ? is there any plugin to do this job?
