The wraps property in UIListLayout is currently a beta feature and doesn’t function in-game yet, I don’t know when it will be ready for public release either but I hope it’s soon because of its usefulness.
Just bumping this since it is still in beta, and I would love to see this implemented. It is such a useful feature and I’ve built most of my GUI taking it into consideration. I don’t wanna lose too much time doing it again.
