Foundation menus provide you with a flexible way of determining what items will show up in your menu. Maybe you only want the top level menu or the sub menu of the currently active page. With power like this, its a piece of cake to build split navigation.
Its easy to define your own custom menu structure using a simple HTML list. Combine this with The Global Text feature in Stacks and you will be all set.
Foundation supports ways of adding labels, headers and dividers to your menus by simply adding easy to use snippets to your page names.
