Submenu enhances the WordPress 3.x navigation system. When you have a website based on WordPress with a lot of pages, but you need a custom menu, it can be tedious to have to add a menu entry for each page created. Submenu just does it automatically.
Submenu also allows you to put menus or portion of menus anywhere in your site: sidebar, templates or page contents.

Gecka Submenu

Works fine for me

Submenu autopopulates any nav menu page item with its children and allows to put menus, or portion of menus, anywhere in your site.
