You’re using the AJAX feature incorrectly, in a couple of ways:

  1. The AJAX feature isn’t meant to load an entire data set; rather, it’s meant to query the server for data that matches the user’s search term, and to fill the dropdown with those results.
  2. Your success callback (lines 7-15 in your code) is generating HTML, but that’s not what Select2 expects. Select2 expects a processResults callback to return a JavaScript object in a specific format. The Select2 widget will take care of converting your data object into the appropriate HTML (which, by the way, is not a series of <option> elements).

Please go back and read the Select2 AJAX documentation, which includes code samples you can follow to use it correctly.
