    \qmltype Menu
    \inherits QtObject
//! \nativetype QQuickLabsPlatformMenu
    \inqmlmodule Qt.labs.platform
    \since 5.8
    \brief A native menu.
 
    The Menu type provides a QML API for native platform menu popups.
 
    \image {qtlabsplatform-menu.png} {A native popup menu}
 
    Menu can be used in a \l MenuBar, or as a stand-alone context menu.
    The following example shows how to open a context menu on right mouse
    click:
 
    \code
    MouseArea {
        anchors.fill: parent
        acceptedButtons: Qt.RightButton
        onClicked: zoomMenu.open()
    }
 
    Menu {
        id: zoomMenu
 
        MenuItem {
            text: qsTr("Zoom In")
            shortcut: StandardKey.ZoomIn
            onTriggered: zoomIn()
        }
 
        MenuItem {
            text: qsTr("Zoom Out")
            shortcut: StandardKey.ZoomOut
            onTriggered: zoomOut()
        }
    }
    \endcode
 
    \section2 Submenus
 
    To create submenus, declare a Menu as a child of another Menu:
 
    \qml
    Menu {
        title: qsTr("Edit")
 
        Menu {
            title: qsTr("Advanced")
 
            MenuItem {
                text: qsTr("Auto-indent Selection")
                onTriggered: autoIndentSelection()
            }
 
            MenuItem {
                text: qsTr("Rewrap Paragraph")
                onTriggered: rewrapParagraph()
            }
        }
    }
    \endqml
 
    \section2 Dynamically generating menu items
 
    You can dynamically generate menu items with \l Instantiator. The following
    code shows how you can implement a "Recent Files" submenu, where the items
    come from a list of files stored in settings:
 
    \snippet qtlabsplatform-menu-instantiator.qml menu
 
    \section2 Availability
 
    A native platform menu is currently available on the following platforms:
 
    \list
    \li macOS
    \li iOS
    \li Android
    \li Linux (only available as a stand-alone context menu when running with the GTK+ platform theme)
    \endlist
