Menu
Class: Menu
Create native application menus and context menus.
Process: Main
Tip
See also: A detailed guide about how to implement menus in your application.
Warning
Electron's built-in classes cannot be subclassed in user code. For more information, see the FAQ.
new Menu()
Creates a new menu.
Static Methods
The Menu class has the following static methods:
Menu.setApplicationMenu(menu)
menuMenu | null
Sets menu as the application menu on macOS. On Windows and Linux, the
menu will be set as each window's top menu.
Also on Windows and Linux, you can use a & in the top-level item name to
indicate which letter should get a generated accelerator. For example, using
&File for the file menu would result in a generated Alt-F accelerator that
opens the associated menu. The indicated character in the button label then gets an
underline, and the & character is not displayed on the button label.
In order to escape the & character in an item name, add a proceeding &. For example, &&File would result in &File displayed on the button label.
Passing null will suppress the default menu. On Windows and Linux,
this has the additional effect of removing the menu bar from the window.
Note
The default menu will be created automatically if the app does not set one. It contains standard items such as
File,Edit,View,WindowandHelp.
Menu.getApplicationMenu()
Returns Menu | null - The application menu, if set, or null, if not set.
Note
The returned
Menuinstance doesn't support dynamic addition or removal of menu items. Instance properties can still be dynamically modified.
Menu.sendActionToFirstResponder(action) macOS
actionstring
Sends the action to the first responder of application. This is used for
emulating default macOS menu behaviors. Usually you would use the
role property of a MenuItem.
See the macOS Cocoa Event Handling Guide for more information on macOS' native actions.
Menu.buildFromTemplate(template)
template(MenuItemConstructorOptions | MenuItem)[]
Returns Menu
Generally, the template is an array of options for constructing a
MenuItem. The usage can be referenced above.
You can also attach other fields to the element of the template and they will become properties of the constructed menu items.
Instance Methods
The menu object has the following instance methods:
menu.popup([options])
optionsObject (optional)windowBaseWindow (optional) - Default is the focused window.frameWebFrameMain (optional) - Provide the relevant frame if you want certain OS-level features such as Writing Tools on macOS to function correctly.

Must be declared ifyis declared.ynumber (optional) - Default is the current mouse cursor position. Must be declared ifxis declared.positioningItemnumber (optional) macOS - The index of the menu item to be positioned under the mouse cursor at the specified coordinates. Default is -1.sourceTypestring (optional) Windows Linux - This should map to themenuSourceTypeprovided by thecontext-menuevent. It is not recommended to set this value manually, only provide values you receive from other APIs or leave itundefined. Can benone,mouse,keyboard,touch,touchMenu,longPress,longTap,touchHandle,stylus,adjustSelection, oradjustSelectionReset.callbackFunction (optional) - Called when menu is closed.
