Data and collections
Jekyll provides two main ways to create and maintain large lists/sets of items: data and collections.
The template comes with a few placeholder data lists for common needs, but if you need to create more/different ones, here's how.
Data
If you want to have a large set of structured or nested items in a single file, use a data file.
Put a .yaml file in the /_data folder with any name, and fill it with data. The structure of the data can be arbitrary.
Example:
# some item
- title: Some name
tags:
- tag A
- tag B
description: Some description
# another item
...Collections
If you want to have a large set of items in separate files that can also generate their own separate pages on your site, use collections.
Put .md files in a folder prefixed with a _, and fill their front matters with data. To generate a separate page for each item in the collection, set output: true in your config file as described here.
