Setter allows to change form values according to selected values in different fields.

// Single value
condition: { when: 'x', is: 'y', then: { set: { [field]: value } } }
// Multiple values
condition: {
when: 'x',
is: 'y',
then: { set: { [field1]: value1, [field2]: value2 } }

Set is a object consists of field names as keys and values as values. You can change any form field value from any conditional action.

When the field containing a condition has some defined initial value, the setter is not triggered until the setter is retriggered with a different value.

To enable dynamic set action you can define set as a function.

type set = (formState: FormState, getFieldState: ((fieldName: string) => FieldState)): void
