Also I didn’t touch any of the other code (yet)
This is from the header.php
<div class="nav-wrap container"><?php wp_nav_menu(array('theme_location'=>'topbar','menu_class'=>'nav container-inner group','container'=>'','fallback_cb'=> false)); ?></div>
And as I said before I have created 3 different menus and assigned them to each nav location.
