drop-down-menu

问题 I'm developing SwiftUI test app and I added my custom DropDown menu here. All works fine except dropdown menu is below other views. So users can't see & click dropdown menu correctly.

NOTE: I need to do it without jQuery (I was just told we are not allowed to use jquery in our project).

问题 I'm wondering how can I do a dropdown button / menu like the ones we can see in the designs specs from Google and in the image bellow, so the list expands bellow right bellow the button.

I tried to make one that looks similar to the one you posted, using AppCompat, working with custom drawables and with the view's elevation
