我现在所知道的是，我可以通过创建 COL 来做到这一点，但我不知道接下来还需要做什么
I like this kind of dynamic drawer very much, that is, the drawer inside the trunk will expand after opening the trunk, but I don't quite understand how to do this effect
All I know now is that I can do this by creating a COL, but I don't know what else I need to do next
Please guide me. Thank you very much!
