Thanks a lot marcelle42, you are right. Now it works 100% correct, all the attributes of the function are working. It was interesting that menu_class was working thou ??

I was thinking if I should add menu items … Just a second

header.php
functions.php

At the moment I don’t have hosting and I’m working on wamp server on my machine :/ but if you don’t see any syntax or logic errors in the source what are the possible problems ?

Thanks for the fast answer but it’s still not working.
If I write this in the header.php:

wp_nav_menu(array('theme_location' => 'header-menu',
			'container' => 'nav',
			'container_id' => 'mainNav',
			'container_class' => 'ulmenu'
			));

It generates the default menu:

<div class="menu">
     <ul>
          <li class="page_item page-item-2">
               <a href="https://localhost/CastingCartel/?page_id=2">Sample Page</a>
          </li>
     </ul>
</div>
