Iterate through multiple value content field in Twig template

I need to take control over the rendering of a field_admin_tags field in a node.html.twig template.


  • {{ content.field_admin_tags }} — Renders everything (label + all field values)
  • {{ content.field_admin_tags.0 }} — Renders only the first value in the field, and no label

PROBLEM: I have no control over the markup surrounding the tags, e.g. <ul><li>...</li></ul>.

So my idea was to iterate over the render array.

But that DOES NOT work:

{% for tag in content.field_admin_tags %}   {{ tag }} {% endfor %} 

I get: Exception: Object of type Drupal\node\Entity\Node cannot be printed.

I think I'm iterating over the keys/values of the render array vs the items inside the field (if I print out an "X" in each loop, I get 20 X's while I only have a couple of two or three values in this field).

I'd like to iterate over content.field_admin_tags.0, content.field_admin_tags.1, etc.

Any idea how to fix this? Thanks.


Any idea how to fix this? Yes, use a field twig. There you can put a loop that iterates over the field items and theme this as you like:


  {% for item in items %}
    <li>{{ item.content }}</li>
  {% endfor %}
