更改 Rubaxa sortable 中拖动列表的背景颜色?

Change the background color of the dragged list in Rubaxa sortable?

我正在使用 Rubaxa sortable 使列表项可排序。现在我想更改被拖动列表的背景颜色。 现在我正在使用文档中可用的幽灵 class,但只有文本背景是彩色的,但我希望整个列表以及编号都具有背景颜色。 谁能知道如何通过 javascript 将自定义 classes 添加到可排序对象中,以便实现相同的效果。

  Sortable.create(simpleList, {
    ghostClass: "ghost"
  });
.ghost {
  color: #fff;
  background-color: #c00;
}
.container {
  text-align: center;
}
ol {
  display: inline-block;
}
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://rubaxa.github.io/Sortable/Sortable.js"></script>
<div class="container">
  <ol id="simpleList" class="list-group">
    <li>A Good Meal</li>
    <li>A technical Improvement</li>
    <li>Nonsense</li>
  </ol>
</div>

Sortable.create(simpleList, {
    ghostClass: "ghost"
  });
.ghost {
  color: #fff;
  background-color: #c00;
}
.container {
  text-align: center;
}
ol {
  display: inline-block;
}

.list-group{width:100%}
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="http://rubaxa.github.io/Sortable/Sortable.js"></script>
<div class="container">
  <ol id="simpleList" class="list-group">
    <li>A Good Meal</li>
    <li>A technical Improvement</li>
    <li>Nonsense</li>
  </ol>
</div>

     onEnd: function ( /**Event*/ evt) {

             var newIndex = index + 1 + '.';
             $(this).find('.index').html(newIndex);
