title: Twitter bootstrap class navbar-collapse erases the <ul>
body: <p>I am trying to learn Bootstrap and I am currently coding the navbar of my new website. But everytime I put a div with nav-collapse navbar-responsive-collapse collapse classes the links in the UL of the navbar just dissapear. Here is the code:</p>
  
  <pre><code>&lt;div class="navbar navbar-fixed-top navbar-inverse"&gt;
          &lt;div class="container"&gt;
  
             &lt;a class="navbar-brand" href="#"&gt;FUTURE LOGO&lt;/a&gt; 
  
             &lt;div class="nav-collapse navbar-responsive-collapse collapse"&gt;
                &lt;ul class="nav navbar-nav"&gt;
  
                   &lt;li class="active"&gt;&lt;a href="#"&gt;&lt;span class="glyphicon glyphicon-home white"&gt;&lt;/span&gt; Domu&lt;/a&gt;&lt;/li&gt;
  
                   &lt;li&gt;&lt;a href="#"&gt;Section&lt;/a&gt;&lt;/li&gt;
                   &lt;li&gt;&lt;a href="#"&gt;Section&lt;/a&gt;&lt;/li&gt;
  
                   &lt;li class="dropdown"&gt;&lt;a href="#" class="dropdown-toggle" data-toggle="dropdown"&gt;Section&lt;strong class="caret"&gt;&lt;/strong&gt;&lt;/a&gt;
                      &lt;ul class="dropdown-menu"&gt;
                        &lt;li&gt;&lt;a href="#"&gt;Subsection&lt;/a&gt;&lt;/li&gt;
                        &lt;li&gt;&lt;a href="#"&gt;Subsection&lt;/a&gt;&lt;/li&gt;
                        &lt;li&gt;&lt;a href="#"&gt;Subsection&lt;/a&gt;&lt;/li&gt;
  
                        &lt;li class="divider"&gt;&lt;/li&gt;
  
                        &lt;li class="dropdown-header"&gt;Dropdown-header&lt;/li&gt;
                        &lt;li&gt;&lt;a href="#"&gt;Subsection&lt;/a&gt;&lt;/li&gt;
                        &lt;li&gt;&lt;a href="#"&gt;Subsection&lt;/a&gt;&lt;/li&gt;
                      &lt;/ul&gt;&lt;!-- End dropdown-menu--&gt;
                   &lt;/li&gt;&lt;!-- End dropdown--&gt;
                &lt;/ul&gt;&lt;!--End nav--&gt;
             &lt;/div&gt;&lt;!-- End navbar-collapse--&gt;
          &lt;/div&gt; &lt;!-- End container--&gt;
      &lt;/div&gt; &lt;!-- End navbar--&gt;
