title: how to display caret via rails link_to for dropdown in bootstrap
body: <p>I want to display the little drop down menu symbol in my rails app that uses twitter bootstrap via the link_to method in my rails app.  </p>
  
  <p>I can't figure out how to do it.  When I add the <code>&lt;b class="caret"&gt;&lt;/b&gt;</code> (that twitter bootstrap uses) to the <code>'Setup '</code> argument below, it gets escaped and shows up as text not html.</p>
  
  <p><code>
      &lt;%= link_to 'Setup ', root_path, :id =&gt; 'setupdrop', :'data-toggle' =&gt; 'dropdown', :class =&gt; 'dropdown-toggle' %&gt;
  </code></p>
  
  <p>Of all the rails examples that I have seen so far, none use link_to when using this feature of TBS (and include the caret).</p>
