I am new to Grav. What I want to do is, having a directory tree with files in it and the directories should somehow be rendered as an Index like in Wiki until I am on the leave Level. Does grav have any functionali8ty to render some kind of menu based on directories and files in it?
I’d say yes. You’ll probably will have to use CSS to style the menu like an index tree. I haven’t used sub menus by now but it should be not that hard. Apart from that there is no quick answer or one click solution, I guess. You’ll have to dig a bit into the documentation.
