I want to hide and show sections (groups) based on scrolling “initiation”.
1 Page is loaded first group is shown (100% vertical height of the screen)
2 User tries to scroll down: first group* is hidden and second group* is shown
3 … and so on and same thing for scrolling up.
In other words: how to detect that the user is trying to scroll down (or up)
Thank you very much for the help
