Hi,
I did not understand the page collection that can be accessed in twig template in this link - https://learn.getgrav.org/content/collections.
I am learning with antimatter theme. I created a listing page using blog.md and made the collection in the blog.md frontmatter. But, in the section accessing collections in twig it says : Grav creates a collection page.collection that you can access in a twig template with:
{% for p in page.collection %}
<h2>{{ p.title }}</h2>
{{ p.summary }}
{% endfor %}
In which file is this code contained in? in the blog.html.twig ?
