title: Is there any way to check if an element has jquery select2 already applied to it?
body: <p>I want to apply <a href="http://select2.github.io/select2/">select2</a> to a bunch of jquery elements on the page that all have the same class name but it looks like if i call select2() on an element that already has had a select2() called on it then it blows up.  here is my code</p>
  
  <pre><code> $('.MyDropdowns').each(function (i, obj) {
      $(obj).select2({ width: "455px" });
  });
  </code></pre>
  
  <p>so I want something like:</p>
  
  <pre><code> $('.MyDripdowns').each(function (i, obj) {
      if (!$(obj).HasSelect2Initiatized)
      {
          $(obj).select2({ width: "455px" });
      }
  });
  </code></pre>
  
  <p>Does anything like this exist?</p>
