How do I make a scrolling gallery?

Hey @cfowler , I’m Jonathan from the Editor X team.
You can actually set the Pro Gallery to slide automatically and loop the images.
Click the Customize Layout on the bottom, and toggle on the loop images and slide automatically options.

You can also achieve this by applying some Velo. If you need assistance you can search on Velo Forum , or post a new topic and someone will help you.
