I'm trying to fetch the label of the list and display it on the twig template.

Using node.field_list.value outputs the key value. I tried using node.field_list.label but it returns empty. I tried using node.field_list.title, node.field_list.0.label or node.field_list[0]['#markup'] but it still returns empty on the twig template

    Ah, I understand your question properly now from the accepted answer, I was thinking of the field label rather than the human names for the values. – Alfred Armstrong Jul 26 '18 at 13:59

There are a few ways:

It calls List allowed values and it stores in the field configuration.

When field cardinality is 1

<div>
  {% set list_value = node.filter_list.value %}
  {{ node.filter_list.getSetting('allowed_values')[list_value] }}
</div>

When field cardinality is more than 1

<div>
  {% set allowed_values = node.filter_list.getSetting('allowed_values') %}
  {% set list_values = node.filter_list.getValue() %}
  {% for list_value in list_values %}
    <div>
      {{ allowed_values[list_value['value']] }}
    </div>
  {% endfor %}
</div>

In case when your template is node.html.twig you can render it based on field formatter in your view mode.

<div>
  {{ content.filter_list }}
</div>
  • Thanks, but what if the field is set to unlimited and not to limited? I tried this {% set list_value = node.field_list.value %} {% for list in node.field_list.getSetting('allowed_values')[list_value] %} {{ list }} {% endfor %} but it does not seem to output anything on the loop – clestcruz Jul 26 '18 at 8:19

    @clestcruz good point, I updated my answer – Alex Kuzava Jul 26 '18 at 8:42
  • Hmm I tried your solution but nothing seems to output within the twig template – clestcruz Jul 26 '18 at 9:11
  • @clestcruz ahh yes, ->value returns only single value, I updated answer, try one more time – Alex Kuzava Jul 26 '18 at 9:38

You can use the module Twig Field Value to help with this task. Once installed the code:

{{ content.field_list|field_label }}

should display the label. The way the label is stored and accessed not affected by the field's cardinality.

  • I tried using Twig Field Value to output the value as you mentioned but it only returns empty. I even tried {{ node.field_list.value|field_label }} – clestcruz Jul 26 '18 at 8:38
  • Try using "content" instead of "node". I just checked the comments in the base node template and that's the correct way to get rendered field data. – Alfred Armstrong Jul 26 '18 at 8:58
  • Yah I tried that also, the thing it is rendered within page.html.twig – clestcruz Jul 26 '18 at 9:00
  • In page.html.twig? That's not where you'd normally render field data directly. If you need to go off-piste it would be better to sort out your data in a preprocess hook instead. – Alfred Armstrong Jul 26 '18 at 9:06

Here is how I've been able to display the label of a Single Choice Text List inside a custom Entity referenced on a node with an EntityReference field :

{% for entity_ref_item in node.field_my_entity_ref_field %}
  {% set my_choice_key = entity_ref_item.entity.field_my_list_field.value %}
  {% set my_choice_label = entity_ref_item.entity.field_my_list_field.getSettings('allowed_values')['allowed_values'][my_choice_key] %}
  <div>{{ my_choice_label }}</div>
{% endfor %}

I believe that Alex Kuzava's code might have been missing one array ['allowed_values']

{{ node.filter_list.getSetting('allowed_values')[list_value] }}

might need to be

{{ node.filter_list.getSetting('allowed_values')['allowed_values'][list_value] }}

instead. To be sure, you can use devel kint()

{{ kint(node.filter_list.getSetting('allowed_values'))}}

That's how I found out there was one more array level before getting to the label. But maybe my situation was different because I am accessing a custom entity...
