推荐答案

您正在查看的是级联下拉列表.
Google也可以尝试.

在内部，其他下拉列表是根据上一个下拉列表填充的.通常，使用AJAX是为了与服务器进行对话并获取数据并通过下拉列表进行绑定.

You you are looking at is Cascading dropdown.
Google for same and try out.

Internally, other dropdown is populated based on previous one. Generally, AJAX is used in order to talk to server and get the data and bind with dropdown.
