README

Working with hierarchical data can get complex quickly. Fortunately, there are tools to help. This bundle wraps 3 amazing tools together.

• a {% tree %} twig tag for recursively displaying a tree without writing a twig macro Wrapper for jstree using ApiPlatform. Also includes a {% tree %} twig tag.
• A stimulus controller that calls the jstree javascript library
• Some helpers to integrate with ApiPlatform for editing and creating tree nodes.

In addition to the above, the has a dependency on stof/doctrine-extensions-bundle to make doctrine entities hierarchical.

composer req survos/tree-bundle

Tree Tag

The {% tree %} tag works almost like {% for %}, but inside a {% tree %} you can call {% subtree var %} See more details at tacman/tree-tag.

{% tree item in menu %}
  {% if treeloop.first %}<ul>{% endif %}
    <li>
        <a href="{{ item.url }}">{{ item.name }}</a>
        {% subtree item.children %}
    </li>
  {% if treeloop.last %}</ul>{% endif %}
{% endtree %}
