title: responsive-nav.js on wordpress menu doesn't work
body: <p>I'm using the <a href="http://responsive-nav.com/" rel="nofollow">http://responsive-nav.com/</a> system in my wordpress theme but I have some bugs with the responsive menu.
  With this html code it works (without wordpress menu):</p>
  
  <pre><code>    &lt;nav class="nav-collapse"&gt;
        &lt;ul&gt;
         &lt;li&gt;&lt;a href="#"&gt;Home&lt;/a&gt;&lt;/li&gt;
         &lt;li&gt;&lt;a href="#"&gt;About&lt;/a&gt;&lt;/li&gt;
         &lt;li&gt;&lt;a href="#"&gt;Projects&lt;/a&gt;&lt;/li&gt;
         &lt;li&gt;&lt;a href="#"&gt;Contact&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&gt;
      &lt;/nav&gt;
  </code></pre>
  
  <p>But with the wordpress menu it doesn't:</p>
  
  <pre><code>    &lt;nav class="nav-collapse"&gt;
        &lt;?php wp_nav_menu( array('menu' =&gt; 'Main' )); ?&gt;
      &lt;/nav&gt;
  </code></pre>
  
  <p>Do you have an idea?</p>
  
  <p>Thanks in advance</p>
