Nesting collections

my file tree looks something like this:

pages
   journeys
      journey
         day

journeys:

content:
   items: @self.children

journey:

content:
   items: @self.children

how can I address nested collections in code?

thank you!

I think the best option is to use taxonomy for your collection rather than @self.children so that way you will have much more control.

could you provide some code as an idea ? Thanks!

You assign a taxonomy to the pages (a tag or a category), and you ask Grav to build a collection from such taxonomy, like explained in Taxonomy Collections

code? ;-)

or: what fits where?
