Select2: How to prevent tags sorting

Question

When user selects many items (tags), they are automatically sorted alphabetically. How to prevent automatic sort and keep user\'s order using Select2 4.0?

Update:

Answer 1

This has been discussed before for Select2 3.5.2, you can use select2('data') to get the order.

$("select").select2();

$('#sayResult').click(function () {
  // 'data' brings the unordered list, while val does not
  var data = $('select').select2('data');
  
  // Push each item into an array
  var finalResult = data.map(function () {
    return this.id;
  });

  // Display the result with a comma
  alert( finalResult.join(',') );
});
