推荐答案

错误非常具体：你不能有多个选择下拉列表。



找到更符合您需求的另一个控件！

（我不能建议一个，因为我有不知道你的网站是什么样的，或者你想做什么，或者让用户做什么）

The error is pretty specific: You can''t have multiple selections in a drop down list.

Find another control which fits your needs better!
(I can''t suggest one, since I have no idea what your site looks like, or what you are trying to do, or let the user do)
