Directory Tree Disable

So I’m still interested in a nested search functionality. However, with reading some other posts that have been published here, I may have stumbled upon something, but I’m not for sure. When going through the tutorials, a lot of them say “if directory tree mode is enabled/disabled” I noticed there was a recursive tree option, but can only be used if directory tree mode is disabled. If I could find how to disable directory tree mode, then technically the “nested search function” should work. Does anyone know how to disable directory tree mode though? I have searched and searched and can’t seem to find where to do this. Hopefully this is helpful to someone, and maybe we can get this search functionality to work!

Thanks!
