title: modify wordpress wp_nav_menu url
body: <p>How could I change the code generated by wp_nav_menu?</p>
  
  <p>Right now it generates:</p>
  
  <pre><code>&lt;ul class="rounded "&gt;
  &lt;li class="arrow"&gt;&lt;a href="http://diner.mobileversion.co/menus/"&gt;Menus&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>I'd like it to look like this:</p>
  
  <pre><code>&lt;ul class="rounded "&gt;
  &lt;li class="arrow"&gt;&lt;a href="/#menus/"&gt;Menus&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>i found this link, but could not get it working properly.</p>
