In Jekyll, can we group multiple collections inside the same folder?

Question

In config.yml, I define my collections like this:

collections:
  music:
    output: false
  dancing:
    output: false

The problem is I will ha

Answer 1

Nothing prevents you to use subfolders in your collection. (Note: this is not an answer to your question but a possible workaround)

So as a workaround you could have just one collection: say _arts for example and organize your folders like:

_arts
     dancing
     music
     concerts
     .....

to list them separately you can use:

1. a FrontMatter variable in your files category: dancing when you have a output and check this for a dancing only list for example.

   {% for project in site.arts %}
   {% if project.category == 'dancing' %}
   ....
   {% endif %}
   {% endfor %}
   

2. or check the path when you have no output for the collection

   {% for project in site.arts %}
   {% if project.url contains 'dancing' %}
   ....
   {% endif %}
   {% endfor %}
   

This could slowdown your build if you have hundreds and hundreds of items inside.
