推荐答案

您的"n级组合框"是众所周知的简单事情:树视图.更确切地说，它是一个带有其他元素的树视图:一个文本框(文本类型的<input>元素)，您应在其中按下键以在树视图中移动选择，就像在组合框中一样.这个附加元素的行为尚不十分清楚，因为组合框还具有几种行为模式(以一种类型实现).而且我不知道您到底需要什么行为.无论如何，您都需要自己设计和实现它.

Your "n-level combo box" is a well-known simple thing: tree view. More exactly, it''s a tree view with additional element: a text box (<input> element of the text type) where you should handle key presses to move selection in the tree view like in a combo box. The behavior of this additional element is not quite clear, because combo boxes also has several behavioral patterns (implemented in one type); and I don''t know what exactly behavior do you need. You need to design and implement it by yourself anyway.
