What is Collapsible Groups?
Collapsible Groups is part of this pack. The pack ships version 1.2.3 for NeoForge on Minecraft 1.21.1, and it has been in the pack since 1.17.0 or earlier.[1]
Unverified The sources I have only confirm that the mod is installed and which version it is. They don't describe what it does, who it's aimed at, or where it fits in the pack's progression. There's no confirmed recipe, config option or quest for it here, so I'm not going to guess at any of that.
