We've adapted Navs from Bootstrap. They have shared markup, starting with the base .nav class, as well as shared states. Swap modifier classes to switch between each style.
For navigation between pages in a section (eg. Roster's Group Search, People Search, and Group Mail), iuse .nav-sub. The example below would normally be floated right (see example at the top of this page).
Take that same HTML, but use .nav-choices instead.
