Repository files navigation

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.

Copy thegroup-by-array.html file into your Jekyll project's_includes directory.

Include the file in your template, passing in acollection and afield variable. Then Jekyll Group-By-Array will setgroup-names andgroup-items global variables with the results.

For example:

---layout: pagetitle: Tagspermalink: /tags/---{%includegroup-by-array.htmlcollection=site.postsfield='tags' %}<ul>  {%fortagingroup_names %}    {%assignposts =group_items[forloop.index0] %}    <li>      <h2>{{tag }}</h2>      <ul>        {%forpostinposts %}        <li>          <ahref='{{site.baseurl }}{{post.url }}'>{{post.title }}</a>        </li>        {%endfor %}      </ul>    </li>  {%endfor %}</ul>
