[Drupal 8]

I have a List (text) field that allows multiple values, displayed as a check box list when editing. But when viewing the node, only the checked values are displayed.

How can I display all values, with an indicator which ones are checked/unchecked? Is this possible with theming?

What I found so far:

  • For Boolean fields, I can select something like this under "Output format" (e.g., "✔ / ✖"), but this doesn’t seem to be possible for List (text) fields. I guess the workaround would be to use multiple Boolean fields, but this makes Views Exposed Filters harder to use.

  • For Drupal 7, there is the module Selected and unselected values formatter (via the question How to display all values of List (text) instead of just the selected ones?)

  • I could imagine (but didn’t try) it would be possible to create a View and display it instead of the field, but then quick-editing would no longer work for this field, as far as I know.

You can easily generate a field formatter to output what you need in drupal 8 (generate field formatter => drupal gpff with drupal console) and get the result into a view.

Getting the field definition will allow you to get all possibles values (selected or not) for your list and display items as check or not considering the current node value.

$defs = \Drupal::service('entity_field.manager')->getFieldDefinitions('{ENTITY_TYPE}', '{BUNDLE}');
$field_definition = $defs['{FIELD_NAME}'];

Your custom formatter will be available in views (and everywhere it is usable, node display etc.).

'Display Selected and Unselected' module - is one of the possible solutions for Drupal 8.
