any tips for creating a scrollable character select screen

I’m new to Unity and right now I’m stuck at the point on creating character select screen. I just want it to be a simple, horizontal scrollable character select screen (like Crossy Roads for example).
I tried on using scrollRect but I can’t get it to work.

It would be great if anyone could help giving me tips on how to achieve that.

The solution I adopted was to attach objects to the transparent buttons in a scrool rect, so as to manage 3d objects with the convenient of scrool rect interface.

Here you can find the official documentation to use the scroll rect: Redirect to... title of new-page
