title: Send form on enter key press with select2
body: <p>I've a form with a select2 element (remote data example: <a href="https://select2.github.io/examples.html" rel="nofollow noreferrer">https://select2.github.io/examples.html</a>). I would like to send the form on enter key press in order to send the custom typed text without selecting a choice from the dropdown list. Is it possible?</p>
  
  <p>Please see the attached image as example: I would like that, pressing enter key, the typed terms "text not present on the dropdown list" will be sended on the form.</p>
  
  <p>Thanks</p>
