What are collections
Collections are custom content types different from pages and posts. You might create a collection if you want to treat a specific set of articles in a unique way, such as with a custom layout or listing. For more detail on collections, see Ben Balter's explanation of collections here.
Create a collection
To create a collection, add the following in your configuration file:
collections:
tooltips:
output: true
In this example, tooltips is the name of the collection.
Interacting with collections
You can interact with collections by using the site.<collection_namespace>
path. In this case, if I wanted to loop through all tooltips, I would use site.tooltips
instead of site.pages
or site.posts
.
See Collections in the Jekyll documentation for more information.
