Hello DevFourm, I have recently encountered a problem with scaling my UIListLayout in my upgrades window for my game. When testing the UI on a smaller screen, the UIListLayout spacing expands beyond the frame, and off the screen.
I would recommend making the main frame a scrolling frame, so if it does go off screen, they can scroll to see the items, the alternative would be re scaling them, but then the items might be too small.
So best option is use a scrolling frame.
A little tip is set the canvas size to {0,0}, {0,0}, and then set the AutomaticCanvasSize property to Y.
This will make the scrolling frame automatically adapt to the items in the scrolling frame so you can see all of them!
