title: Bootstrap 3 topnav that turns into sidebar when in small screens?
body: <p>I'm relatively experienced with Bootstrap 2, and can usually get it to do what I want, but I'm having an issue with Bootstrap 3.</p>
  
  <p>I'm trying to have a top nav across the page, and a secondary top nav underneath it.  The secondary top nav, when the screen is big enough, should pop over to be a sidebar.</p>
  
  <p>I'm pretty stuck, and don't know where to go from <a href="http://getbootstrap.com/examples/offcanvas/" rel="nofollow">http://getbootstrap.com/examples/offcanvas/</a>.</p>
  
  <p>Thanks!</p>
  
  <p>EDIT:  This is what I have.  It shows the idea, but the nav is defined twice.  Take a look, you'll see what I mean.  <a href="http://jsfiddle.net/xwp7S/2/" rel="nofollow">http://jsfiddle.net/xwp7S/2/</a></p>
  
  <p>I have the sidebar defined as:</p>
  
  <pre><code>        &lt;div class="col-xs-6 col-sm-3 sidebar-offcanvas" id="sidebar" role="navigation"&gt;
              &lt;div class="well sidebar-nav"&gt;
                  &lt;ul class="nav"&gt;
                      &lt;li&gt;Sidebar&lt;/li&gt;
                      &lt;li class="active"&gt;&lt;a href="#"&gt;Link 1&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 2&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 3&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 4&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 5&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 6&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#"&gt;Link 7&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
              &lt;/div&gt;
              &lt;!--/.well --&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p>and the top nav defined as</p>
  
  <pre><code>&lt;div class="navbar navbar-fixed-top navbar-inverse" 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=".topnav-collapse"&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;Project name&lt;/a&gt;
          &lt;/div&gt;
          &lt;div class="collapse navbar-collapse topnav-collapse"&gt;
              &lt;ul class="nav navbar-nav"&gt;
                  &lt;li class="active"&gt;&lt;a href="#"&gt;Home&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#about"&gt;About&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#contact"&gt;Contact&lt;/a&gt;&lt;/li&gt;
              &lt;/ul&gt;
          &lt;/div&gt;
          &lt;!-- /.nav-collapse --&gt;
      &lt;/div&gt;
      &lt;!-- /.container --&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>and extra css of</p>
  
  <pre><code> @media screen and (max-width: 768px) {
      #sidebar {
          display: none;
      }
  }
  
  @media screen and (min-width: 768px) {
      #topsidebar {
          display: none;
      }
  }
  </code></pre>
  
  <p>How do I approach the problem of not defining the nav twice?</p>
