In class
A validation rule for checking if a value is within a specified list of items.
The In
class is a concrete implementation of the FormifyRule
abstract class.
It is used to validate whether a value is contained within a specified list of items.
This rule checks if the input value
is included in the provided items
list.
If the value
is not found within the list, an error message is generated.
