show unlimited children category on twig

Question

I have array like this:

array(
  'id' => 1,
  'children' => array(
    'id' => 5,
    'children' =>
    array(
      'id' => 6,
      'children' => 'none',
    ),
    array(
      'id' => 8,
      'children' => array(...),
    )
  )
)

with php code can call Recursive Function to echo it. but in twig i can't call Recursive Function.

{% for category in categories %}
    <div class="category">
      <div class="id">{{ category.id }}</div>
    </div>
{% endfor %}

my code just print first level of array and not other!

you could include the same view again so that the behavior is the same as in your recursive function. Like in this [answer](https://stackoverflow.com/a/8467939/2401386) — Blauharley, May 18 '18 at 13:28

You can with blocks:

{% set foo = { 'hello': { 'hello': { 'hello': 'swagg' }, 'foo': 'bar' } } %}


{% block test %}
<ul>
    {% for keyOfFoo, f in foo %}
    <li>
        {{ keyOfFoo }}
        {% if f is iterable %}
            {% with { foo: f } %}
            {{ block('test') }}
            {% endwith %}
        {% endif %}
    </li>
    {% endfor %}
</ul>
{% endblock test %}

But there is also many other options. Like include loop. Or embedded.
