推荐答案

简单来说，就是不要提供下拉菜单的"width"属性.

它会自动处理它，并将按照其中的值设置宽度.

更新:
正如Ankur所指出的，我建议的是基于其中的最大长度值使宽度下降.但是，听起来问题是要根据下拉菜单中的选定"值在运行时调整宽度.如果是这样，您将不得不使用其他人建议的Javascript.但是，我不建议您采用这种行为，因为在运行时在选择时具有大小可变的控件很烦人，并且不被认为是一种好的UI设计.

Simply, just don''t provide the ''width'' property of the dropdown.

It will automatically take care of it and will set the width as per the values in it.

UPDATE:
As Ankur pointed out, what I have suggested is for having a dropdown of width based on the maximum length value in it. But, sounds like the question is to adjust the width at runtime based on the ''selected'' value in dropdown. If so, you would have to use Javascript as suggested by others. BUT, I would not recommend this behavior as having a varying sized control at runtime on selection is irritating and is not considered a good UI design.

您应该尝试使用javascript或jquery.

找到所选项目文本的宽度(以像素为单位)，并将其设置为下拉菜单的宽度.

You should try javascript or jquery.

Find the width of the selected item text in pixel and set it to dropdown''s width.
