Is there a UI component with a dropdown curtain?

Question

Android

We need a component, such as a button, when pressed, a curtain will move on top of other components. In the curtain, respectively, there will be other components.
How to do it in a regular way or mb is there a side either?

Answer 1

I am using https://github.com/chenjishi/SlidingUpPaneLayout. On the main fragment at the top I place the image of the curtain and when it is opened, it remains visible at the bottom.
