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.
解决方法
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.

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.
