Open node groups without tabbing into them?

I see pictures like this one of node groups that seem to be open without being tabbed into them. Is this just something from an old version, or is there still a way to do this? For organizational purposes, it would be handy to be able to see what’s inside simple groups/frames like this.

Just an old version, that’s what node groups looked like when you tabbed into them back in the day. The current UI showed up in…2.66? 2.67? Somewhere in there, I think. You couldn’t actually interact with nodes outside of that frame without tabbing back out, same as today.

Alright, thanks.
