Have you tried using Flexbox for this section? Support is getting pretty good and it’s a very simple fix if it’s a possibility.
Just make sure the main container (collection-list) is set to “Flex”
Then match the settings below
That’s it! Now your items will adjust depending on the height of the element and wrap exactly how (I hope) you’re wanting it to.
Let me know if you have any issues!
Edit: Just figured I’d add some extra links for you to check out. Flexbox is super powerful, and thankfully Webflow has an entire course on it you can follow here. If you’re interested in the support for Flexbox, head over here. Cheers!
