title: Bootstrap Collapse - open the given id fragment
body: <p>Imagine a <a href="http://getbootstrap.com/javascript/#collapse">Bootstrap collapse</a> with 3 parts</p>
  
  <pre><code>&lt;div class="panel-group" id="accordion"&gt;
      ...
      &lt;div id="accordionOne" class="panel-heading"&gt;&lt;/div&gt;
      ...
      &lt;div id="accordionTwo" class="panel-heading"&gt;&lt;/div&gt;
      ...
      &lt;div id="accordionThree" class="panel-heading"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is there a simple way to make the plugin open the given <a href="http://dev.w3.org/html5/spec/single-page.html#scroll-to-fragid">HTTP fragment identifier</a> ?</p>
  
  <p>Example <code>http://myproject/url#accordionTwo</code> would open the second accordion</p>
