# MenuItem

The Wisej.NET `MenuItem` must be added to a `MainMenu`, `MenuBar`, or `ContextMenu` for display. Create submenus by adding `MenuItem` objects to a parent `MenuItem`'s `MenuItems` property.

Configure appearance and functionality through properties:

* `Checked`: Displays a check mark (useful for mutually exclusive options like text color selection)
* `Shortcut`: Defines keyboard selection combination

In MDI applications, use `MergeMenu` to combine MDI parent and child form menus. Since a `MenuItem` cannot exist in multiple locations simultaneously (like `MainMenu` and `ContextMenu`), use `CloneMenu` to create copies.

Events enable dynamic control:

* `Popup`: Perform pre-display tasks (show/hide items based on application state)
* `Select`: Execute actions when users hover (e.g., display detailed help)
