Jquery ui jqueryui可排序+；引导变量高度Divs排序问题

需要您的帮助来解决有关UI可通过引导进行排序的问题，我可以在引导中实现此可排序功能，但仍然存在一个我自己无法解决的问题。我的小提琴链接：

http://jsfiddle.net/wrtfp513/

问题：这里（检查我的小提琴）我分为三个部分（.part1，.part2，.part3）我可以在这三个部分中的任何地方对我的“测试”内容进行排序，但当我将所有“测试”内容排序为“part1”时，出现了一个问题“无法分别排序为.part2和.part3”

我的代码：

<div class="container">
    <div id="drag_holder" class="row">
        <div class="col-lg-2 col-md-3 col-sm-4 col-xs-4 part1">
           <div class="col-lg-12 drag_content"> 
              <div class="panel panel-default">
                  <div class="panel-heading">Test 1</div>
                  <div class="panel-body">Lorem Ipsum is simply dummy text of the printing and typesetting indu  Ipsum.</div>
              </div>
            </div>
            <div class="col-lg-12 drag_content"> 
              <div class="panel panel-default">
                  <div class="panel-heading">Test 2</div>
                  <div class="panel-body">Contfghfghent</div>

提前感谢各位。

现在您正在使用Jquery UI进行拖放（可排序）。我理解你的问题。这可能是您指出的jQueryUI中的一个问题。因此，您可以使用dragula.js来实现拖放功能，而不是使用jqueryui。它有一个了不起的功能，同时放置目标元素及其阴影

请点击此处：

$(function () {
var demos =$("#drag_holder");
    demos.sortable({
         items: ".drag_content",
       placeholder: "panel"
    });

});
