title: Menu region showing up inappropriately
body: <p>I am trying to customize a wordpress theme. In header.php it checks if a menu exists in a certain region and if there isnt one it is supposed to not show anything. However the region is still showing up even though there is no menu there. Any advice is appreciated, thanks!</p>
  
  <pre><code>&lt;nav id="resurrect-header-menu" class="resurrect-clearfix"&gt;
    &lt;div id="resurrect-header-menu-inner" class="resurrect-clearfix"&gt;
      &lt;?php
        wp_nav_menu( array(
                      'theme_location'    =&gt; 'header',
                      'menu_id'           =&gt; 'resurrect-header-menu-links',
                      'menu_class'        =&gt; 'sf-menu',
                      'container'         =&gt; false, // don't wrap in div
                      'fallback_cb'       =&gt; false, // don't show pages if no menu found - show nothing
                      'walker'            =&gt; new CTFW_Walker_Nav_Menu_Description
                   ) );
      ?&gt;
    &lt;/div&gt;
  &lt;/nav&gt;
  </code></pre>
