jquery multiselect – 嵌套

我正在使用以下 jquery 插件在我的select控件中选择多个选项： jquery multiselect

如何实现嵌套<选项>这里？我知道这是可能的,因为渲染的html使用< li>标签

情况是我想在我的组合框中得到类似的结果：

[ ] England
   [ ] London
   [ ] Leeds
   [ ] Manchaster

有谁知道如何实现这种解决方案.任何帮助都会很有帮助.

描述

假设我明白你想要什么,你可以使用optgroup来做到这一点.

看看我为你创造的这个jsFiddle Demonstration.

样品

<select multiple="multiple" size="5">
<optgroup label="England">
    <option value="London">London</option>
    <option value="Leeds">Leeds</option>
    <option value="option3">Manchaster</option>
</optgroup>
<optgroup label="USA">
    <option value="option4">New York</option>
    <option value="option5">Chicago</option>
</optgroup>
</select>

更新

我创建了一个 jsFiddle Demonstration.

经过与niao的深入讨论后更新

niao: yes,that’s what I need. I will have to add some css to make it looks pretty. You can append your answer and I will be more than happy to accept it

您可以在此jSFiddle中查看结果.

I encourage you to download the resources (javascript and css files) to put that on your enviroment.
