Note: acceleratorWorksWhenHidden is specified as being macOS-only because accelerators always work when items are hidden on Windows and Linux. The option is exposed to users to give them the option to turn it off, as this is possible in native macOS development. This property is only usable on macOS High Sierra 10.13 or newer.

Roles

Roles allow menu items to have predefined behaviors.

It is best to specify role for any menu item that matches a standard role, rather than trying to manually implement the behavior in a click function. The built-in role behavior will give the best native experience.

The label and accelerator values are optional when using a role and will default to appropriate values for each platform.

Every menu item must have either a role, label, or in the case of a separator a type.

The role property can have following values:

• undo
• redo
• cut
• copy
• paste
• pasteAndMatchStyle
• selectAll
• delete
• minimize - Minimize current window.
• close - Close current window.
• quit - Quit the application.
• reload - Reload the current window.
• forceReload - Reload the current window ignoring the cache.
• toggleDevTools - Toggle developer tools in the current window.
• togglefullscreen - Toggle full screen mode on the current window.
• resetZoom - Reset the focused page's zoom level to the original size.
• zoomIn - Zoom in the focused page by 10%.
• zoomOut - Zoom out the focused page by 10%.
• fileMenu - Whole default "File" menu (Close / Quit)
• editMenu - Whole default "Edit" menu (Undo, Copy, etc.).
• viewMenu - Whole default "View" menu (Reload, Toggle Developer Tools, etc.)
• windowMenu - Whole default "Window" menu (Minimize, Zoom, etc.).

The following additional roles are available on macOS:

• appMenu - Whole default "App" menu (About, Services, etc.)
• about - Map to the orderFrontStandardAboutPanel action.
• hide - Map to the hide action.
• hideOthers - Map to the hideOtherApplications action.
• unhide - Map to the unhideAllApplications action.
• startSpeaking - Map to the startSpeaking action.
• stopSpeaking - Map to the stopSpeaking action.
• front - Map to the arrangeInFront action.
• zoom - Map to the performZoom action.
• toggleTabBar - Map to the toggleTabBar action.
• selectNextTab - Map to the selectNextTab action.
• selectPreviousTab - Map to the selectPreviousTab action.
• mergeAllWindows - Map to the mergeAllWindows action.
• moveTabToNewWindow - Map to the moveTabToNewWindow action.
• window - The submenu is a "Window" menu.
• help - The submenu is a "Help" menu.
• services - The submenu is a "Services" menu. This is only intended for use in the Application Menu and is not the same as the "Services" submenu used in context menus in macOS apps, which is not implemented in Electron.
• recentDocuments - The submenu is an "Open Recent" menu.
• clearRecentDocuments - Map to the clearRecentDocuments action.

When specifying a role on macOS, label and accelerator are the only options that will affect the menu item. All other options will be ignored. Lowercase role, e.g. toggledevtools, is still supported.

Nota Bene: The enabled and visibility properties are not available for top-level menu items in the tray on MacOS.
