CMS Collection List into a Bento Grid design

Hi! I’m struggling to create a bento grid style of a layout for my CMS Collection List. I want to adjust each Collection Item into different sizes; e.g. 1 item being across two rows, another across 2 columns, one within just one cell etc.

With a non-CMS Collection List Grid, you can just drag items across columns and rows but I can’t find the little drag mark within the grid edit mode when the grid holds a CMS Collection List.

Please help me, it’s an urgent one… :sweat_smile: Thank you!
