In a form design wizard, users can define cue fields and then indicate their importance. Some fields will always be in the form (for other purposes). However, for one of these areas, a person may indicate 3 "levels" of operation:
- Mandatory (the field is mandatory and can not be left empty by the end user)
- Optional (the field is optional / can be left empty)
- Disabled (the field can not be changed by the user / will always be empty).
Since each of these options is mutually exclusive, the use of multiple checkboxes / sliders is not correct.
One option is to use 3 radio buttons – however, this requires a lot of "room" for such a simple definition.
Is there a better tool? Where can I easily show the ternary status and have an easy return (also on mobile)?
