## Detailed Description

Menu has two main use cases:

- Context menus; for example, a menu that is shown after right clicking
- Popup menus; for example, a menu that is shown after clicking a button

When used as a context menu, the recommended way of opening the menu is to call popup(). Unless a position is explicitly specified, the menu is positioned at the mouse cursor on desktop platforms that have a mouse cursor available, and otherwise centered over its parent item.

     MouseArea {
         anchors.fill: parent
         acceptedButtons: Qt.LeftButton | Qt.RightButton
         onClicked: {
             if (mouse.button === Qt.RightButton)
                 contextMenu.popup()
         }
         onPressAndHold: {
             if (mouse.source === Qt.MouseEventNotSynthesized)
                 contextMenu.popup()
         }

         Menu {
             id: contextMenu
             MenuItem { text: "Cut" }
             MenuItem { text: "Copy" }
             MenuItem { text: "Paste" }
         }
     }

When used as a popup menu, it is easiest to specify the position by specifying the desired x and y coordinates using the respective properties, and call open() to open the menu.

     Button {
         id: fileButton
         text: "File"
         onClicked: menu.open()

         Menu {
             id: menu
             y: fileButton.height

             MenuItem {
                 text: "New..."
             }
             MenuItem {
                 text: "Open..."
             }
             MenuItem {
                 text: "Save"
             }
         }
     }

If the button should also close the menu when clicked, use the `Popup.CloseOnPressOutsideParent` flag:

     onClicked: menu.visible = !menu.visible

     Menu {
         // ...
         closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent

Since QtQuick.Controls 2.3 (Qt 5.10), it is also possible to create sub-menus and declare Action objects inside Menu:

     Menu {
         Action { text: "Cut" }
         Action { text: "Copy" }
         Action { text: "Paste" }

         MenuSeparator { }

         Menu {
             title: "Find/Replace"
             Action { text: "Find Next" }
             Action { text: "Find Previous" }
             Action { text: "Replace" }
         }
     }

Sub-menus are cascading by default on desktop platforms that have a mouse cursor available. Non-cascading menus are shown one menu at a time, and centered over the parent menu.

Typically, menu items are statically declared as children of the menu, but Menu also provides API to add, insert, move and remove items dynamically. The items in a menu can be accessed using itemAt() or contentChildren.

Although MenuItems are most commonly used with Menu, it can contain any type of item.

## Margins

As it is inherited from Popup, Menu supports margins. By default, all of the built-in styles specify `0` for Menu's margins to ensure that the menu is kept within the bounds of the window. To allow a menu to go outside of the window (to animate it moving into view, for example), set the margins property to `-1`.

## Dynamically Generating Menu Items

You can dynamically create menu items with Instantiator or dynamic object creation.

### Using Instantiator

You can dynamically generate menu items with 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:

     Menu {
         title: qsTr("File")

         Menu {
             id: recentFilesMenu
             title: qsTr("Recent Files")
             enabled: recentFilesInstantiator.count > 0

             Instantiator {
                 id: recentFilesInstantiator
                 model: settings.recentFiles
                 delegate: MenuItem {
                     text: settings.displayableFilePath(modelData)
                     onTriggered: loadFile(modelData)
                 }

                 onObjectAdded: (index, object) => recentFilesMenu.insertItem(index, object)
                 onObjectRemoved: (index, object) => recentFilesMenu.removeItem(object)
             }

             MenuSeparator {}

             MenuItem {
                 text: qsTr("Clear Recent Files")
                 onTriggered: settings.clearRecentFiles()
             }
         }
     }

### Using Dynamic Object Creation

You can also dynamically load a component from a QML file using Qt.createComponent(). Once the component is ready, you can call its createObject() method to create an instance of that component.

     Row {
         anchors.centerIn: parent

         Component {
             id: menuItemComponent

             MenuItem {}
         }

         Button {
             id: button
             text: "Menu"
             onClicked: menu.open()
             Menu {
                 id: menu
             }
         }

         Button {
             text: "Add item"
             onClicked: {
                 onClicked: {
                     let menuItem = menuItemComponent.createObject(
                         menu.contentItem, { text: qsTr("New item") })
                     menu.addMenu(menuItem)
                 }
             }
         }
     }

## Property Documentation

[since QtQuick.Controls 2.3 (Qt 5.10)] cascade : bool

This property holds whether the menu cascades its sub-menus.

The default value is platform-specific. Menus are cascading by default on desktop platforms that have a mouse cursor available. Non-cascading menus are shown one menu at a time, and centered over the parent menu.

Note: Changing the value of the property has no effect while the menu is open.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also overlap.

[default] contentData : list<QtObject>

This property holds the list of content data.

The list contains all objects that have been declared in QML as children of the menu, and also items that have been dynamically added or inserted using the addItem() and insertItem() methods, respectively.

Note: Unlike `contentChildren`, `contentData` does include non-visual QML objects. It is not re-ordered when items are inserted or moved.

See also Item::data and contentChildren.

[read-only] contentModel : model

This property holds the model used to display menu items.

The content model is provided for visualization purposes. It can be assigned as a model to a content item that presents the contents of the menu.

     Menu {
         id: menu
         contentItem: ListView {
             model: menu.contentModel
         }
     }

The model allows menu items to be statically declared as children of the menu.

[read-only, since QtQuick.Controls 2.3 (Qt 5.10)] count : int

This property holds the number of items.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

[since QtQuick.Controls 2.3 (Qt 5.10)] currentIndex : int

This property holds the index of the currently highlighted item.

Menu items can be highlighted by mouse hover or keyboard navigation.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also MenuItem::highlighted.

[since QtQuick.Controls 2.3 (Qt 5.10)] delegate : Component

This property holds the component that is used to create items to present actions.

     Menu {
         Action { text: "Cut" }
         Action { text: "Copy" }
         Action { text: "Paste" }
     }

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also Action.

focus : bool

This property holds whether the popup wants focus.

When the popup actually receives focus, activeFocus will be `true`. For more information, see Keyboard Focus in Qt Quick.

The default value is `true`.

See also activeFocus.

icon group
icon.cache : bool
icon.color : color
icon.height : int
icon.name : string
icon.source : url
icon.width : int

This property group was added in QtQuick.Controls 6.5.

Name | Description
--- | ---
name | This property holds the name of the icon to use. The icon will be loaded from the platform theme. If the icon is found in the theme, it will always be used; even if icon.source is also set. If the icon is not found, icon.source will be used instead. For more information on theme icons, see QIcon::fromTheme().
source | This property holds the name of the icon to use. The icon will be loaded as a regular image. If icon.name is set and refers to a valid theme icon, it will always be used instead of this property.
width | This property holds the width of the icon. The icon's width will never exceed this value, though it will shrink when necessary.
height | This property holds the height of the icon. The icon's height will never exceed this value, though it will shrink when necessary.
color | This property holds the color of the icon. The icon is tinted with the specified color, unless the color is set to `"transparent"`.
cache | This property specifies whether the icon should be cached. The default value is true. For more information, see cache. This property was introduced in QtQuick.Controls 2.13.

See also AbstractButton::text, AbstractButton::display, and Icons in Qt Quick Controls.

[since QtQuick.Controls 2.3 (Qt 5.10)] overlap : real

This property holds the amount of pixels by which the menu horizontally overlaps its parent menu.

The property only has effect when the menu is used as a cascading sub-menu.

The default value is style-specific.

Note: Changing the value of the property has no effect while the menu is open.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also cascade.

title : string

This property holds the title for the menu.

The title of a menu is often displayed in the text of a menu item when the menu is a submenu, and in the text of a tool button when it is in a menubar.

Opens the menu at the specified position pos in the popups coordinate system, that is, a coordinate relative to its parent item.

The menu can be optionally aligned to a specific menu item.

This QML method was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also Popup::open().

`[since QtQuick.Controls 2.3 (Qt 5.10)]` void popup(Item parent, real x, real y, MenuItem item = null)
`[since QtQuick.Controls 2.3 (Qt 5.10)]` void popup(real x, real y, MenuItem item = null)

Opens the menu at the specified position x, y in the popups coordinate system, that is, a coordinate relative to its parent item.
