I am trying to do something like this, roughly:
<main navigation> <jumbotron> <subnavigation> <page structure of subnavigation>
What I did so far is creating a base-page-custom.php, a corresponding page-custom.php and a corresponding templates/header-custom.php which is correctly referenced in the page-custom.php.
I also created respective pages and a menu, which I gave the name Custom Navigation and changed the name respectively in templates/header-custom.php.
Unfortunately, the secondary nav-menu doesn’t show. When I check the sourcecode with firebug, it only shows this:
<nav class="nav-main" role="navigation"> </nav>
What did I miss or am I doing wrong?
