How do I edit collection source from dynamic list

Hi there Webflow fam.

How do I change the cms collection in my project? It’s currently “locked”. Please see screenshot 1. I’m aware that I have to find the bottom element (child element) linked to that Collection and unlink it from bottom to top like what this YouTube video shows:

But for my case, I don’t see how I can change that at the most bottom child element. Please see screenshot 2.

Could anyone please point me in the right direction?

This is my project’s link on view mode: Webflow - InspireMind Experiment

hi @Ericjee your collection ‘Documentary Category’ is ONLY staged for publish. You need to publish it first be able to unlink it. :man_shrugging:
