I’ve configured some (repeating) containers to scroll when overflowing, but it doesn’t seem to be working as you can see here:
The container has a minimum width and the elements inside as well. But instead of scrolling it squeezes everything.
This is only for vertical scroll at the moment! You might want to use the rotate into rows/columns feature with the mobile viewport selected to get it displaying nicely on mobile
Oh… I didn’t even understand that changing the viewport was to apply different styles to the mobile version. I thought it was only to preview how it would like on mobiles 
Good to know!
