Option for how container is displayed in scrivening mode

Would someone remind me where the option is that controls how (or is it if?) a container file or folder is displayed in scrivening mode.

I know it’s there somewhere, but I’m just not seeing it.

Thank you!

Navigation options: “Treat all documents with children as folders”. And otherwise, there is no explicit settings for which view mode should be used, the software always just uses the last mode you enabled.
