title: How can I add parent menu description to my Wordpress menu?
body: <p>I've entered the description into the parent menu items in Wordpress, but they're not showing on my theme.</p>
  
  <p>I know that a walker class can be used to make changes to the menu, but I don't know how to code it.</p>
  
  <p>Here is what I want to achieve:</p>
  
  <pre><code>&lt;nav id="main-menu" role="navigation"&gt;
  &lt;div class="menu-main-menu-container"&gt;
      &lt;ul id="menu-main-menu" class="menu"&gt;
          &lt;!-- REPEATING MENU ITEM START --&gt;
          &lt;li class="menu-parent-item"&gt;&lt;a&gt;Face&lt;/a&gt;
          &lt;ul class="sub-menu"&gt;
              &lt;li class="menu-image-container"&gt;
                  &lt;div class="menu-image"&gt;&lt;/div&gt;
                  &lt;div class="menu-description"&gt;[Face menu item description]&lt;/div&gt;
              &lt;/li&gt;
              &lt;li class="heading"&gt;Face&lt;/li&gt;
              &lt;ul class="sub-menu"&gt;
                  &lt;li class="menu-item"&gt;Sub menu 1&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 2&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 3&lt;/li&gt;
              &lt;/ul&gt;
              &lt;li class="heading"&gt;Ear&lt;/li&gt;
              &lt;ul class="sub-menu"&gt;
                  &lt;li class="menu-item"&gt;Sub menu 1&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 2&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 3&lt;/li&gt;
              &lt;/ul&gt;
              &lt;li class="heading"&gt;Eyes&lt;/li&gt;
              &lt;ul class="sub-menu"&gt;
                  &lt;li class="menu-item"&gt;Sub menu 1&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 2&lt;/li&gt;
                  &lt;li class="menu-item"&gt;Sub menu 3&lt;/li&gt;
              &lt;/ul&gt;
          &lt;/ul&gt;
          &lt;/li&gt;
          &lt;!-- REPEATING MENU ITEM END --&gt;
      &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p></p>
  
  <p>As you can see, I only want the description of the parent menu item to be shown, but it needs to be within the first <code>ul.sub-menu</code> within the parent list item.</p>
  
  <p>How could I code a walker that uses <code>start_lvl</code>, <code>start_el</code> and <code>end_lvl</code> to handle this efficiently?</p>
