  this.opts = this.group.find('ul.dropdown > li');
  this.val = '';
  this.index = -1;
  this.initEvents();
}
DropDowngroup.prototype = {
  initEvents: function () {
  var obj = this;
  obj.group.on('click', function (event) {
  $(this).toggleClass('active');
  return false;  });
  obj.opts.on('click', function () {
    var opt = $(this);
    obj.val = opt.text();
    obj.index = opt.index();
    obj.placeholder.text(obj.val);
    //取值到我所隱藏的Html.HiddenFor(x=>x.name) 表單送出我就直接抓取此欄位的值
    $("#Group").val(opt.children().attr('id'));
  });
},
getValue: function () {
  return this.val;
},
getIndex: function () {
  return this.index;
