body: <p>I'm new to bootstrap and I'm trying to add navbar to my website so
  I copied the code from <a href="http://getbootstrap.com/components/#navbar" rel="nofollow">Bootstrap</a> website but It dropdown menu doesn't work</p>
  
  <p>Here is the code</p>
  
  <pre><code>&lt;nav class="navbar navbar-default" id="navbar"&gt;
        &lt;div class="container-fluid"&gt;
          &lt;!-- Brand and toggle get grouped for better mobile display --&gt;
          &lt;div class="navbar-header"&gt;
            &lt;button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#mynav" aria-expanded="false"&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;a class="navbar-brand" href="#"&gt;Brand&lt;/a&gt;
          &lt;/div&gt;
  
          &lt;!-- Collect the nav links, forms, and other content for toggling --&gt;
          &lt;div class="collapse navbar-collapse" id="mynav"&gt;
            &lt;ul class="nav navbar-nav"&gt;
              &lt;li class="active"&gt;&lt;a href="#"&gt;Link &lt;span class="sr-only"&gt;(current)&lt;/span&gt;&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Link&lt;/a&gt;&lt;/li&gt;
              &lt;li class="dropdown"&gt;
                &lt;a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"&gt;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;Action&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#"&gt;Another action&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#"&gt;Something else here&lt;/a&gt;&lt;/li&gt;
                  &lt;li role="separator" class="divider"&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#"&gt;Separated link&lt;/a&gt;&lt;/li&gt;
                  &lt;li role="separator" class="divider"&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#"&gt;One more separated link&lt;/a&gt;&lt;/li&gt;
                &lt;/ul&gt;
              &lt;/li&gt;
            &lt;/ul&gt;
  
          &lt;/div&gt;&lt;!-- /.navbar-collapse --&gt;
        &lt;/div&gt;&lt;!-- /.container-fluid --&gt;
  </code></pre>
