推荐答案
属性。数据列表目前不支持任何CSS样式,并且特定的视觉特性是特定于浏览器的。某些浏览器可能会选择为长列表添加滚动条。
Unfortunately, there's not much you can do with the datalist attribute. The datalist does not currently support any CSS styling, and specific visual characteristics are browser-specific. Some browsers may choose to add scrollbars for long lists.
如果这不可接受,您可能必须忘记datalist并通过Javascript实现ComboBox。我相信JQuery有一个自动完成功能,可能是适当的。
If this isn't acceptable, you may have to forget the datalist and implement a ComboBox via Javascript. I believe JQuery has an autocomplete function that may be appropriate.
