What happened with my searchbox?

Hi everyone, im using select2 latest version 4.10.13… Here the thing, i’m facing this strange bug everytime i’m clear my input text. It give me multiple searching options. bug

The link of my js: https://paste.ofcode.org/39xT9xZKSJniZsp9JYB3xKk
I’m combine AJAX+ Json with multiple select options of Select2.

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.
