This might not be a Roots-issue, but maybe some of you people know what might be wrong:
I have a menu, with one regular page (with a submenu), and three links to different category archives. When clicking the regular page menu-item, the menu behaves as it should, but if I click one of the categories, the menu disappears.
The HTML output is like this (when I click on one of the category menu-items).
<nav class="collapse navbar-collapse" role="navigation"> </nav>
The wp_debug tells me nothing about whats going on.
