I have the problem where columns stay too close to the minimum comun width, so if 150 px is fine on mobile, it’s too small on desktop but I can’t conditionally change that value and have to make 2 different versions of the repeaatable group.
Bubble’s built-in RG behavior works well in most cases, but if you’d like more explicit control over the number of RG columns at different page widths, this tip might be helpful (if you’re not averse to getting your hands dirty with a bit of CSS).
