List posts by tag

Overview

We can iterate over site.tags, each item is an array with two elements. The first element in the array is the tag name, the second element is a list of the posts in that tag.

...
{% for tag in site.tags %}
  <h2>{{ tag[0] }}</h2>
  <ul>
    {% for post in tag[1] %}
      <li><a href="{{ post.url }}">{{ post.title }}</a></li>
    {% endfor %}
  </ul>
{% endfor %}
