 $("select").select2({
  tags: true
});

$("select").on("select2:select",function (evt) {
  var element = evt.params.data.element;
  var $element = $(element);
  
  $element.detach();
  $(this).append($element);
  $(this).trigger("change");
});
<select style="width: 500px;" multiple="multiple">
    <option>two</option>
    <option>four</option>
    <option>six</option>
  </select>

解决方法

$("select").select2({
  tags: true
});

$("select").on("select2:select",function (evt) {
  var element = evt.params.data.element;
  var $element = $(element);
  
  $element.detach();
  $(this).append($element);
  $(this).trigger("change");
});
//drop down always visibile until you click outside
var thing = $("select").select2({
  closeOnSelect: false
}).on("change",function(e){
  // thing.select2("close");
  // try this line if your code not working
  // thing.select2("open");
});
