    `click(menuItem, window, event)` when the menu item is clicked.
    * `menuItem` MenuItem
    * `window` [BaseWindow](base-window.md) | undefined - This will not be defined if no window is open.
    * `event` [KeyboardEvent](structures/keyboard-event.md)
  * `role` string (optional) - Can be `undo`, `redo`, `cut`, `copy`, `paste`, `pasteAndMatchStyle`, `delete`, `selectAll`, `reload`, `forceReload`, `toggleDevTools`, `resetZoom`, `zoomIn`, `zoomOut`, `toggleSpellChecker`, `togglefullscreen`, `window`, `minimize`, `close`, `help`, `about`, `services`, `hide`, `hideOthers`, `unhide`, `quit`, `showSubstitutions`, `toggleSmartQuotes`, `toggleSmartDashes`, `toggleTextReplacement`, `startSpeaking`, `stopSpeaking`, `zoom`, `front`, `appMenu`, `fileMenu`, `editMenu`, `viewMenu`, `shareMenu`, `recentDocuments`, `toggleTabBar`, `selectNextTab`, `selectPreviousTab`, `showAllTabs`, `mergeAllWindows`, `clearRecentDocuments`, `moveTabToNewWindow` or `windowMenu` - Define the action of the menu item, when specified the
    `click` property will be ignored. See [roles](#roles).
  * `type` string (optional) - Can be `normal`, `separator`, `submenu`, `checkbox` or
    `radio`.
  * `label` string (optional)
  * `sublabel` string (optional) _macOS_ - Available in macOS >= 14.4
  * `toolTip` string (optional) _macOS_ - Hover text for this menu item.
  * `accelerator` [Accelerator](accelerator.md) (optional)
  * `icon` ([NativeImage](native-image.md) | string) (optional)
  * `enabled` boolean (optional) - If false, the menu item will be greyed out and
    unclickable.
  * `acceleratorWorksWhenHidden` boolean (optional) _macOS_ - default is `true`, and when `false` will prevent the accelerator from triggering the item if the item is not visible.
  * `visible` boolean (optional) - If false, the menu item will be entirely hidden.
  * `checked` boolean (optional) - Should only be specified for `checkbox` or `radio` type
    menu items.
  * `registerAccelerator` boolean (optional) _Linux_ _Windows_ - If false, the accelerator won't be registered
    with the system, but it will still be displayed. Defaults to true.
  * `sharingItem` SharingItem (optional) _macOS_ - The item to share when the `role` is `shareMenu`.
  * `submenu` (MenuItemConstructorOptions[] | [Menu](menu.md)) (optional) - Should be specified
    for `submenu` type menu items. If `submenu` is specified, the `type: 'submenu'` can be omitted.
    If the value is not a [`Menu`](menu.md) then it will be automatically converted to one using
    `Menu.buildFromTemplate`.
  * `id` string (optional) - Unique within a single menu. If defined then it can be used
    as a reference to this item by the position attribute.
  * `before` string[] (optional) - Inserts this item before the item with the specified id. If

    that the menu item in question should be placed in the same “group” as the item.

    the placement of their containing group before the containing group of the item
    with the specified id.
  * `afterGroupContaining` string[] (optional) - Provides a means for a single context menu to declare
    the placement of their containing group after the containing group of the item
    with the specified id.

> [!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.

### 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`
* `about` - Trigger a native about panel (custom message box on Window, which does not provide its own).
* `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%.
* `toggleSpellChecker` - Enable/disable builtin spell checker.
* `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.)
* `hide` - Map to the `hide` action.
* `hideOthers` - Map to the `hideOtherApplications` action.
* `unhide` - Map to the `unhideAllApplications` action.
* `showSubstitutions` - Map to the `orderFrontSubstitutionsPanel` action.
* `toggleSmartQuotes` - Map to the `toggleAutomaticQuoteSubstitution` action.
* `toggleSmartDashes` - Map to the `toggleAutomaticDashSubstitution` action.
* `toggleTextReplacement` - Map to the `toggleAutomaticTextReplacement` 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.
* `showAllTabs` - Map to the `showAllTabs` 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"](https://developer.apple.com/documentation/appkit/nsapplication/1428608-servicesmenu?language=objc) 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.
* `shareMenu` - The submenu is [share menu][ShareMenu]. The `sharingItem` property must also be set to indicate the item to share.

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.

> [!NOTE]
> The `enabled` and `visibility` properties are not available for top-level menu items in the tray on macOS.
