I'm trying to access the key of a list (Text) in a paragraph twig file

This is what I have in my list
small|Small Item
big|Big Item

{% set value = content.field_option.0['#markup'] %}
{{ value }}

I always got the text. Small Item or Big Item. I would like to obtain small or big of course depending of the user selection.

I'm going to use this value as an HTML Class.

Thanks for your help

I changed the entity_view_display of my paragraph so that my field output the key, instead of the value. I was then able to access the key. I hope that helps?

I'm able to use this: content.field_button_chrome[0]['#markup']


There are (at least) two options:

  • Option 1: Change the Display of that field from default to key and use {{ content.field_name.0 }}
  • Option 2: Do not use content settings and get the what the entity (paragraph, node etc.) sees: {{ paragraph.field_name.0.value }} for radio/select fields or for multi value fields:
    {% for k,v in paragraph.field_variant %}
      {{ v.value }}
    {% endfor %}
