Checkbox and checkboxes.

Checkbox is just a widget type that is already available for boolean data types. See https://www.drupal.org/docs/extending-drupal/contributed-modules/contrib... → for the breakdown of whats available for each data type.

Checkboxes will not be supported as those values would require a separate table for storage. Custom fields are stored in a single table so therefore each column will only ever allow a single value.

For this same reason I ask.

The list of checkboxes is an essential utility.

It doesn't have it either and the module:

https://www.drupal.org/project/datafield →

I understand that it is difficult at the structural level to make it possible to have the possibility of checkboxes.

Thanks for the work done.
