推荐答案

您应该重新考虑您的设计.下拉列表不是显示大量数据的理想控件.您的用户将很难在下拉菜单中找到数据.

下拉菜单中的项目较少时，它的工作速度更快吗?如果是，则可能要考虑使用一组下拉列表控件来过滤数据.例如，您可以在州下拉列表中过滤城市下拉列表中的条目，而不是在一个下拉列表中加载一个国家的所有城市.

You should reconsider your design. Dropdown is not an ideal control to display large amount of data. Your users will have a hard time finding data in your dropdown.

Does it work faster when the dropdown has fewer items? If yes, you may want to consider having a set of dropdown controls that filter out data. For example, instead of loading all cities in a country in a single dropdown, you can have a State dropdown that filters the entries in the City dropdown.
