title: Bootstrap collapse menu doesn't work
body: <p>I've just installed bootstrap 3 but the collapsing menu doesn't work;
  The menu looks fine in a desktop screen but scaling the hole thing down the menu button doesn't show up..</p>
  
  <p>Here is the code for the menu:</p>
  
  <pre><code>&lt;div id="menu"&gt;
  &lt;div class="navbar navbar-static-top" role="navigation"&gt;
    &lt;div class="container"&gt;
    &lt;a class="btn btn-navbar" data-toggle="collapse" data-target="#nav-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;/a&gt;
  
      &lt;a class="navbar-brand" href="/"&gt;&lt;img class="top-logo" src="img/hotels.nl_.jpg" alt="Hotels.nl"&gt;&lt;/a&gt;
      &lt;div id=".nav-collapse"&gt;
          &lt;ul class="nav navbar-nav pull-right"&gt;
  
      &lt;li class="active"&gt;&lt;a href="#"&gt;Inloggen &lt;span class="sr-only"&gt;(current)&lt;/span&gt;&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href="#"&gt;Contact&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;Taal &lt;span class="caret"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;ul class="dropdown-menu"&gt;
          &lt;li&gt;&lt;a href="#"&gt;Nederlands&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;English&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;German&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&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;Valuta&lt;span class="caret"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;ul class="dropdown-menu"&gt;
          &lt;li&gt;&lt;a href="#"&gt;Euro&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Dollar&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Pond&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;/div&gt;&lt;!--End container--&gt;
  &lt;/div&gt;&lt;!--End fixedtop--&gt;
  </code></pre>
