You can add a maximum of 5 target fields per rule.
The field selected as the target field and the field selected as the operand field cannot be the same within a rule.
The action defined for the parent field takes precedence over the action defined for the child field, in case of contradictions. For example, if your rule says to hide the Group field and show a sub-field of that Group field when a condition is met, it will not show the sub-field.
If you delete a field or edit the properties of a field that has been used as an operand field or a target field, the rule would not be applicable. You must then delete the rule.
