Develop a User built hierarchy

Questions

Hello all,

I’ve been using Bubble about 3 months now. I’m struggling with how to build a UI that enables the User to build a hierarchy that has a top level block, then multiple nested blocks below that. The intent is to allow the user to add only one top level block, then as many level 1 blocks, level 2 blocks or up to level n blocks as needed. I’ve added an image to clarify what I’m trying to accomplish. Any direction provided will be appreciated. Thank you.

I went with nested repeated groups to approximate the hierarchy noted above. As for the lines connecting the blocks, I’ve passed on creating that feature…:wink:
