title: JQuery Append To Multiple Elements Fails
body: <p>I'm trying to use jQuery's append() method to append common content to set of div's as follows:</p>
  
  <pre><code>$("#horizontal_menu").append(menu);
  $("#vertical_menu").append(menu);
  </code></pre>
  
  <p>What I'm finding is that the content (in this case, menu) is getting appended to vertical_menu but not horizontal_menu.  Does appending to one &lt;div&gt; preclude you from appending that content to another &lt;div&gt;?</p>
