Process: [Main](../glossary.md#main-process)

See [`Menu`](menu.md) for examples.

### `new MenuItem(options)`

* `options` Object
  * `click` Function (optional) - Will be called with
    `click(menuItem, browserWindow, event)` when the menu item is clicked.
    * `menuItem` MenuItem
    * `browserWindow` [BrowserWindow](browser-window.md)
    * `event` Event
  * `role` String (optional) - 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)
  * `accelerator` [Accelerator](accelerator.md) (optional)
  * `icon` ([NativeImage](native-image.md) | String) (optional)

    menu items.

    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.
  * `position` String (optional) - This field allows fine-grained definition of the
    specific location within a given menu.

### 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.

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%.
* `editMenu` - Whole default "Edit" menu (Undo, Copy, etc.).
* `windowMenu` - Whole default "Window" menu (Minimize, Close, etc.).

The following additional roles are available on _macOS_:

* `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.
* `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.

### Instance Properties

The following properties are available on instances of `MenuItem`:

#### `menuItem.enabled`

A `Boolean` indicating whether the item is enabled, this property can be
dynamically changed.

#### `menuItem.visible`

A `Boolean` indicating whether the item is visible, this property can be
dynamically changed.

#### `menuItem.checked`

A `Boolean` indicating whether the item is checked, this property can be
dynamically changed.

A `checkbox` menu item will toggle the `checked` property on and off when
selected.

A `radio` menu item will turn on its `checked` property when clicked, and
will turn off that property for all adjacent items in the same menu.

You can add a `click` function for additional behavior.

#### `menuItem.label`

A `String` representing the menu items visible label.

#### `menuItem.click`

A `Function` that is fired when the MenuItem receives a click event.
