title: How to make select2 results look like "Tag + 3 more options selected"?
body: <p>I've been asked to change select2 widget default behavior. Instead of showing multiple selected items stacked like it does by default:</p>
  
  <pre><code>* Alaska
  * Hawaii
  * California
  * Nevada
  </code></pre>
  
  <p>to re-configure in to input showing</p>
  
  <pre><code>* Alaska + 3 more items selected. 
  </code></pre>
  
  <p>The whole point of the idea is to keep the input always of the same height. </p>
  
  <p>I'm not even sure where to start. I've read the documentation, couldn't find anything helpful in API. Though it is sparse. Any help would be much appreciated.</p>
  
  <p>Thank you.</p>
