Multi-sprite images for UI use

Unity Engine
1

I have noticed that if you have a sprite that has been sliced into multiple images these images can not be used in a UI element such as a button or image object. Is there a way to do so or are we stuck using a single image for each button? I have attempted this a couple of times but just doesn’t work the way I would expect.

So you can only use single image files for UI elements?

That shouldn’t be the case. The UI system works with 2D sprites, whether they are spritesheets or not. (just tested to verify)
Just drag the individual sprite instead of the whole image
