title: Two navbars collapsed into 1 for mobile?
body: <p>I have two menus in Bootstrap 3 - a Social Menu and a Main Menu.
  When collapsed on mobile, I get two menu open/toggle buttons to open the corresponding menu items.</p>
  
  <p>Is there any way when collapsed, I can move the Social Menu Items into the Main Menu and use just one toggle/menu button and list? Code is Below...</p>
  
  <pre><code>&lt;div id="social-menu" class="navbar navbar-default navbar-static-top" role="navigation"&gt;
     &lt;div class="container"&gt;
        &lt;div class="navbar-header"&gt;
           &lt;button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-social"&gt;
           &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&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;/div&gt;
        &lt;div class="collapse navbar-collapse navbar-menubuilder"&gt;
           &lt;ul class="nav navbar-nav navbar-social"&gt;
              &lt;li&gt;Social Menu Item 1&lt;/li&gt;
              &lt;li&gt;Social Menu Item 2&lt;/li&gt;
              &lt;li&gt;Social Menu Item 3&lt;/li&gt;
              &lt;li&gt;Social Menu Item 4&lt;/li&gt;
           &lt;/ul&gt;
        &lt;/div&gt;
     &lt;/div&gt;
  &lt;/div&gt;
  
  
  &lt;div id="main-menu" class="navbar navbar-default navbar-static-top" role="navigation"&gt;
     &lt;div class="container"&gt;
        &lt;div class="navbar-header"&gt;
           &lt;button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-main-menu"&gt;
           &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&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;/div&gt;
        &lt;div class="collapse navbar-collapse navbar-menubuilder"&gt;
           &lt;ul class="nav navbar-nav navbar-main-menu"&gt;
              &lt;li&gt;Main Menu Item 1&lt;/li&gt;
              &lt;li&gt;Main Menu Item 2&lt;/li&gt;
              &lt;li&gt;Main Menu Item 3&lt;/li&gt;
              &lt;li&gt;Main Menu Item 4&lt;/li&gt;
           &lt;/ul&gt;
        &lt;/div&gt;
     &lt;/div&gt;
  &lt;/div&gt;
