asp.net 是否存在多选 dropDownList？
我想要一个 DropDownList，每个项目旁边都有一个复选框，允许选择多个项目。我做了一些探索，但没有找到任何可以做到这一点的东西，有谁知道这是否可以轻松实现？
我知道可以使用列表框来完成，但更喜欢下拉格式以节省空间。
I'd like to have a DropDownList that has a CheckBox next to each item that would allow multiple to be selected. I did a little poking around but haven't found anything that will do this, does anyone know if this can be easily achieved?
I know it can be done with a listBox, but would prefer the dropdown format to save space.

我从未在任何平台上见过多选 DropDownList。你希望它如何运作？
我确信一些聪明的 JavaScript 可以创建一个。
I've never seen a multi-select DropDownList on any platform. How do you want it to work?
I'm sure some clever javascript could create one.
查看 ASP.NET AJAX 工具包中的 DropDown 控件：它允许您将任意控件放入类似下拉的界面中。我没有尝试过，但我认为在其中放置一个 CheckBoxList 应该可行。
Have a look at the DropDown control from the ASP.NET AJAX toolkit: It allows you to put arbitrary controls into a dropdown-like interface. I didn't try it, but I think that it should work to put a CheckBoxList in there.
