Symfony2 Twig unlimited child depth

Question

I have a self-joining table where each folder has a parent, and the depth of this is unlimited. One folder can have another folder as a parent, no restriction on the depth.<

Answer 1

You need a separate file rendering options that recursively includes itself:

    No parent
    {% include 'options.html.twig' with {'folders': folders, 'level': 0} %}

options.html.twig:

{% for folder in folders %}
    
        {% for i in range(0, level) %} {% endfor %}
        {{ folder.name }}
    

    {% include 'options.html.twig' with {'folders': folder.children, 'level': level + 1} %}
{% endfor %}

I wrote this code right here, so don't expect it to be correct, but it should be enough to give you the idea.
