Menu Overview

A menu is a pop-up window that allows users to perform specific actions. It typically appears when users right-click, long-press, or touch an item.

API	Use Case
Menu control (Menu)	Used to bind actions to specified components, such as displaying operation options when an icon is long-pressed.
Global menu independent of UI components (openMenu)	Used to show options in scenarios where UI components cannot be directly accessed, for example, in event callbacks.

Menus can be displayed only after the page is fully built. Setting the show property to true during page construction may result in issues with the menu’s position and shape.
When using openMenu, you need to provide valid TargetInfo. Otherwise, the menu won’t display correctly.
