A Checkboxes library field is an ordered set of text strings from which a user might select any or all. A Checkboxes entry field contains either an empty string or a concatenated, comma-separated string values chosen from this list.
The value of a Checkboxes field may be used as a dependency to determine visibility of other fields during entry creation and edit.
During import or sync with Google, if a value is found that is not in the list, it will be created.
During import, export, or sync with Google Sheets, the list is externalized by concatenation using a comma separator (", ").
Advanced Parameters
Where you can edit — Unlike most field types, Checkboxes fields can be displayed and edited (changed, checked/unchecked) in the list directly, though by default, a field will be displayed in the Entry View and Entry Edit cards and may be edited in the Entry Edit Card.
