我不确定我是否完全理解你的问题，但是听起来你想要两个组合/列表框.当用户从列表一中选择一个项目时，您可以使用该值填充列表二.一个简单的例子就是列出一个包含世界上各个国家的清单，然后列出两个包含所选国家/地区的主要城镇/城市的清单.

I''m not sure I understand your question fully but it sounds like you want two Combo/List boxes. When the user selects an item from list one, you use that value to poulate list two. A simple example would be list one containing countries of the world and list two containing the major towns/cities of the selected country.
