I have run into two problems with a recursive page collection. I have found possible solutions for both, but I would be grateful to be told if there are better solutions.

My folder structure is:

books-folder
    book1
    book2
    special-books-folder
        specialbook1
    book3

To collect the set of books I have a collection page containing:

content:
    items: '@self.descendants'

To display the collection I was originally using this:

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

That works fine for book1, book2, book3, ...., generating a link with address /books-folder/book1.

But I have two problems.

Problem 1

That version also lists special-books-folder, with the title "Special Books Folder". Obviously I don't want to list it. My solution:

    {% for child in page.collection %}
        {% if child.header.content is defined %} {# ignore - don't list folder names #}
        {% else %}

Problem 2

The previous version generates bad links for second level books such as specialbook1, generating a link with the address /books-folder/special-books-folder/book1. My solution:

    {% for child in page.collection %}
        <a href="{{ page.route }}/{{ child.slug }}</a>
    {% endfor %}

Are these solutions the best ones? Are there cases where they fail?

Many thanks for your help.

Oops. I now see I have NOT solved Problem 2. For some reason I thought I had. Any offers?

This seems to be an effective answer:

{% for child in page.collection %}
    <a href="{{ child.route }}/style:style1">{{ child.title }}</a>
{% endfor %}

So I think I've solved it. At least, I think I have.

Let us know if any more problems persist :)
