Jekyll Group-By-Array

A liquid include file for Jekyll that allows an object to be grouped by an array. For instance, it could be used to list posts by tag.

Usage

Copy the group-by-array.html file into your Jekyll project's _includes directory.

Include the file in your template, passing in a collection and a field variable. Then Jekyll Group-By-Array will set group-names and group-items global variables with the results.

For example:

---
layout: page
title: Tags
permalink: /tags/
---

{% include group-by-array.html collection=site.posts field='tags' %}

<ul>
  {% for tag in group_names %}
    {% assign posts = group_items[forloop.index0] %}

    <li>
      <h2>{{ tag }}</h2>
      <ul>
        {% for post in posts %}
        <li>
          <a href='{{ site.baseurl }}{{ post.url }}'>{{ post.title }}</a>
        </li>
        {% endfor %}
      </ul>
    </li>
  {% endfor %}
</ul>
