Nooptreq

What it does

This class provides a standardized source model for configuration fields that have three states: No (disabled), Optional, or Required.

Developers use this class in their system.xml configuration files to create dropdown selects where administrators can choose whether a feature should be disabled, optional, or mandatory.

It's commonly used for form field validation settings or feature toggles that need more granularity than a simple yes/no option.
