Disable viewing child groups from within parent?

There have been several updates to DT3 since my last visit, and one of them (I think) changed how Groups are viewed. I’m now noticing that if I have sub-groups/folders, that if I’m in the parent group, I see the contents of all the sub-groups below. I’d like to disable this feature. How do I go about doing that?

Thanks!

Sounds like you’ve expanded those subgroups in the past.

Does this help?

Can you clarify what you mean?
