如果你想要一些免费的东西，可能应该自己编写插件。这是你能得到你想要的几种方法之一。



否则你应该把这个问题分解成更小的部分并开始准确写出你的内容正在寻找。



根据您所寻找的示例，以及快速谷歌搜索，有jstree。



jsTree [ ^ ]



拖放treeview jquery - Google搜索 [ ^ ]

Hi, I would like to know if there is any way i could be able to select multiple options at the same time in a multi-level dropdown and toogle menu. Please see example Drag & Drop support in ASP.NET MVC TreeView control[^]

What I have tried:

Telerik seems to be useful but I am looking for something that is free.

If you want something that is free, probably should write the plugin yourself. That is one of the few ways you'll get exactly what you want.

Otherwise you should just break down this issue into smaller pieces and begin to write exactly what you are looking for.

Based on your example of what you are looking for, and in doing a quick google search there is jstree.
