The Menu events are used to control what happens when a user interacts with a parent menu's Down button to navigate deeper into a menu structure. These events allow you to intercept, customize, or extend the behavior of menu navigation, whether you want to validate actions, control access, or execute additional logic when a sub-menu is opened.
