How can I change the border color of this. I generally got it from this answer

 $(document).ready(function() { $("select").select2(); });

You can style elements with CSS, so if you want every select2-selection class to have a certain border-color , you can add the following:

.select2-selection {
  border-color: green; /* example */
}
