title: MVC: How to make DropdownList field (with Chosen Plugin) Required
body: <p>I have declared a parameter in my model  as</p>
  
  <pre><code>[Required]
  public int? param{get; set;}
  </code></pre>
  
  <p>and defined this on a dropdown list. Everything works fine and the data validation works, until I add the plugin, <a href="http://davidwalsh.name/jquery-chosen" rel="noreferrer">Chosen</a>. When I add the plugin, there is no validation proior to submission. How can i keep the data validation when the plugin is applied on the Select element?</p>
