title: bootstrap navbar - show only submenu on mobile
body: <p>I have a standard bootstrap navbar, that collapse on mobile. Here below the code, for your reference:</p>
  
  <pre><code>&lt;nav class="navbar navbar-inverse"&gt;
    &lt;div class="container-fluid"&gt;
  
      &lt;div class="navbar-header"&gt;
        &lt;button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;                        
        &lt;/button&gt;
        &lt;a class="navbar-brand" href="#"&gt;WebSiteName&lt;/a&gt;
      &lt;/div&gt;
  
      &lt;div class="collapse navbar-collapse" id="myNavbar"&gt;
        &lt;ul class="nav navbar-nav"&gt;
          &lt;li class="dropdown"&gt;
            &lt;a class="dropdown-toggle" data-toggle="dropdown" href="#"&gt;Menu with dropdown &lt;span class="caret"&gt;&lt;/span&gt;&lt;/a&gt;
            &lt;ul class="dropdown-menu"&gt;
              &lt;li&gt;&lt;a href="#"&gt;Submenu voice 1&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Submenu voice 2&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Submenu voice 3&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/div&gt;
  
    &lt;/div&gt;
  &lt;/nav&gt;
  </code></pre>
  
  <p>I would like, after clicking on the hamburger menu on mobile, to get directly the 3 <code>&lt;li&gt;</code> "Submenu voice x" and hide the parent <code>&lt;li&gt;</code> (class="dropdown").</p>
  
  <p>How can I achieve this result? Thank you</p>
