This seems like the simplest thing but I can’t seem to work it out! I just want to be able to center a repeating group. That’s it.
I’ve tried row, column, align to parent etc…
I’ve also tried putting it in a row of its own with center alignment. I don’t want it to fill the horizontal width necessarily, as that would make the columns too wide, or the gap between them too wide.
It’s difficult to say without seeing a screenshot of your setup, but unless either the RG or one of its containing groups has its width constrained (has a max width set - either less than 100% or a hard pixel value), it will always be as wide as the page.
And of course, a different max width can be set for different page widths via conditionals.
