title: Put multiple data-role into razor DropDownList
body: <p>Is there a way to put multiple data-role into a razor code? I need it to tag my select list for a jquery tagger.</p>
  
  <p>I need to make following: </p>
  
  <pre><code>@Html.DropDownList("Orientations", (SelectList)ViewBag.Orientations, "None", new { @multiple data-role="tagsinput", @class = "form-control" })
  </code></pre>
  
  <p>from: </p>
  
  <pre><code>@Html.DropDownList("Orientations", (SelectList)ViewBag.Orientations, "None", new { @class = "form-control" })
  </code></pre>
  
  <p>But it does not work by that way.<br>
  Thank you!</p>
