How to use selectize - 1 common examples

"use strict";
var $ = require("jquery"), selectize = require("selectize"), utils = require("yasgui-utils");

selectize.define("allowRegularTextInput", function(options) {
  var self = this;

  this.onMouseDown = (function() {
    var original = self.onMouseDown;
    return function(e) {
      if (!self.$dropdown.is(":visible")) {
        //receiving focus via mouse click
        original.apply(this, arguments);

        //this is a trick to make each value editable
        //a bit strange, but the only trick to avoid static values
        //and, this allows copy-ing (ctrl-c) of endpoints as well now
        var val = this.getValue();
        this.clear(true);
        this.setTextboxValue(val);
        this.refreshOptions(true);
