title: How to use bootstrap's dropdown on table cell (td)?
body: <p>I have a simple html table layouted with bootstrap:</p>
  
  <pre><code>[...]
  &lt;td data-toggle="dropdown" class="tag dropdown-toggle"&gt;
  &lt;span class="number"&gt;Employee1&lt;/span&gt;
  &lt;ul class="dropdown-menu"&gt;&lt;li&gt;&lt;a href="#"&gt;to nightshift&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  &lt;/td&gt;
  [...]
  </code></pre>
  
  <p>But when I click on the cell, the dropdown does not appear.
  How can I let the dropdown appear like it is done here?</p>

  <p>Do I need listen to <em>td.click</em> manually?</p>
