title: How to remove select2 from dom
body: <p>Say we have a simple <code>select2</code> list:</p>
  
  <pre><code>&lt;select id="e1"&gt;
    &lt;option value="AL"&gt;Alabama&lt;/option&gt;
      ...
    &lt;option value="WY"&gt;Wyoming&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Initiated like: </p>
  
  <pre><code>$("#e1").select2();
  </code></pre>
  
  <p>How can I remove <code>select2</code> and return it to a regular dropdown? I can't find any examples or entry in documentation.</p>
  
  <p>Something like:</p>
  
  <pre><code>$("#e1").select2('remove'); 
  </code></pre>
  
  <p>would be nice.</p>
