@page variable not working in Page collections

Hi all,

I am trying to build a vertical menu which would complement the horizontal menu with drop-down in the Deliver theme (more about that in /forum/themes-styling/menu-in-deliver-theme-t6666?u=sue).

Fot this purpose, I am using Page Collections, i. e. modified codes copied from https://learn.getgrav.org/16/content/collections

Out of the table Summary of collection options, those based on '@root', '@self' and '@taxonomy' work fine (i. e. generate the list of topics). However, I need to take advantage of the '@page' functionality and that is not working.

This is the frontmatter of the relevant page:

content:
    items:
        '@page': '/software'
    order:
        by: name
        dir: asc
    pagination: false

and this is the code for generating the menu:

<div class="sidebar-content">

            <ul>
                    {% for post in page.collection %}
                    <li><a href="{{ post.url }}">{{ post.title }}</a></li>
                    {% endfor %}
            </ul>

What am I doing wrong?
THX!

@sue, Using a default fresh Grav installation, I did the following which seems to work as expected...

• I created the following folder structure:
  TXTCopy

  pages
  ├── 01.home
  │   └── default.md
  ├── 02.typography
  │   └── default.md
  └── software
    ├── software1
    │   └── default.md
    └── software2
        └── default.md
  

• In file '02.typography/default.md' I created a collection by copying your code:
  YAMLCopy

  ---
  title: Typography
  content:
    items:
        '@page': '/software'
    order:
        by: name
        dir: asc
    pagination: false
  ---
  

• And copied your loop to 'themes/quark/templates/default.html.twig'

  TWIGCopy

  {% extends 'partials/base.html.twig' %}
  
  {% block content %}
    <ul>
        {% for post in page.collection %}
            <li><a href="{{ post.url }}">{{ post.title }}</a></li>
        {% endfor %}
    </ul>
  
    {{ page.content|raw }}
  {% endblock %}
  

And this is the result when I browse to page 'typography':

So, it seems your code and collection definition are OK...

How does your folder structure look like? Is '/software' located directly underneath '/pages'?

Hi, yes, the /software is located directly underneath the /pages. The loop is in
themes/deliver/templates/partials/sidebar.html.twig.

Thanks.

Hi, a funny thing happened: the variable /filename did not work and nothing improved over the weekend. I decided to give a shot to default.html.twig, so I copied the loop there, reloaded the page... and it was working! Both in the sidebar.html.twig and the default.html.twig!
Although I do not understand why it started working, I am happy that it did ;)
