title: Does select2 dropdown support using ajax and allowing users to enter in new values?
body: <p>I <a href="https://select2.github.io/examples.html" rel="nofollow noreferrer">am using select 2</a> and it works great.  I have an example where as user is chosing from a dropdown via ajax (exactly like the Remote Data example listed in the link) but I want the user to be able to search as well as be able to type in a new value that doesn't exist on the back end.  </p>
  
  <p>I have this working on the multiselect but trying to see if there is the same support when using the single dropdown option?</p>
