In config.yml, I define my collections like this:
collections:
music:
output: false
dancing:
output: false
The problem is I will ha
Answer is no. Your collections folder must be at the root of your root folder.
Even if you name you create a collection in _collections/_music folder, and set it up like this :
collections:
collections/_music folder:
output: true
Jekyll ends up looking for your collection in _collections_music folder
(without any slash) because of path sanitize process.
See jekyll code in collection.rb, site.rb and jekyll.rb
