After many hours of searching the forums, I found this: Listing nested directories
Then I did what @budparr suggested:
{{ $sections := (.Site.GetPage "section" "community").Sections }}
{{ range first 15 $sections | shuffle}}
And that shows the countries only now. I never heard of the .GetPage function. I do not see this mentioned on https://gohugo.io/variables/site/ unless I missed something.
What does this function really do? .GetPage from section called community and then get .Sections from that? I didn’t even know you could do that. Cool.
