Multiple timeline on drag action


I am hype new user and trying to make an app prototype have the same scroll wheel effect when you set an apple alarm clock. (scroll and the selected number get larger and rest became small/grey) I have two scrollable area, the one that on the top layer on the main timeline works but not the other one. Anyone know how to fix this problem so that my two scroll wheel would work? Thank you!!

Maybe an example so that we can see what you’re doing already, exactly.

HI Dbear,

Thank you for responding me. Here is the example what I am talking about but double the scroll wheel.

Sorry cuz I am using company’s computer so I cannot upload any images online

Thank you so much!!

I think what I meant is I wondering how to switch between timelines and at the meanwhile the on drag action also works.

Thank you!!!
