title: select2 - use as autocomplete textbox (even if not an option)
body: <p>I'm trying to use the select2 add-on as more of a textbox (compared to a dropdown) with autocomplete features. This means that if a user types something that is not in the list, I want this custom value to remain as the value for the form.</p>
  
  <p>I've searched stackoverflow and found the following:</p>
  
  <p><a href="https://stackoverflow.com/questions/18470917/disable-no-matches-found-text-and-autocomplete-on-select2">Disable &quot;No matches found&quot; text and autocomplete on select2</a></p>
  
  <p><a href="https://stackoverflow.com/questions/17950117/select2-when-no-option-matches-other-should-appear">Select2, when no option matches, &quot;other&quot; should appear</a></p>
  
  <p>Neither of them keep the "custom" value.</p>
