title: style rails checkboxes with bootstrap
body: <p>I have checkboxes in rails like this:</p>
  
  <pre><code>&lt;%= f.label "Area of Expertise" %&gt;&lt;br /&gt;
   &lt;%= f.collection_check_boxes :expertise_ids, Expertise.all, :id, :name do |b| %&gt;
    &lt;form role="form form-group"&gt;
     &lt;label class="checkbox-inline"&gt;
      &lt;%= b.check_box %&gt;
       &lt;%= b.label %&gt;
     &lt;/label&gt;
    &lt;/form&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>But the checkboxes are all displaying in a list going down and not across like its supposed to using the <code>checkbox-inline</code> class.</p>
