Menu
Process: Main
Creates a new menu.
Static Methods
The Menu
class has the following static methods:
Menu.setApplicationMenu(menu)
menu
Menu | 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
, Window
and Help
.
Menu.getApplicationMenu()
Returns Menu | null
- The application menu, if set, or null
, if not set.
Note: The returned Menu
instance doesn’t support dynamic addition or
removal of menu items. Instance properties can still
be dynamically modified.
Menu.sendActionToFirstResponder(action)
macOS
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 .
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.
Instance Methods
The menu
object has the following instance methods:
options
Object (optional)window
(optional) - Default is the focused window.x
number (optional) - Default is the current mouse cursor position. Must be declared ify
is declared.y
number (optional) - Default is the current mouse cursor position. Must be declared ifx
is declared.positioningItem
number (optional) macOS - The index of the menu item to be positioned under the mouse cursor at the specified coordinates. Default is -1.callback
Function (optional) - Called when menu is closed.
Pops up this menu as a context menu in the BrowserWindow
.
menu.closePopup([browserWindow])
browserWindow

.
menu.append(menuItem)
menuItem

Appends the menuItem
to the menu.
menu.getMenuItemById(id)
id
string
Returns MenuItem | null
the item with the specified id
menu.insert(pos, menuItem)
pos
IntegermenuItem
Inserts the menuItem
to the pos
position of the menu.
Objects created with new Menu
or returned by Menu.buildFromTemplate
emit the following events:
Note: Some events are only available on specific operating systems and are labeled as such.
Event: ‘menu-will-show’
Returns:
event
Event
Emitted when menu.popup()
is called.
Event: ‘menu-will-close’

event
Event
Emitted when a popup is closed either manually or with menu.closePopup()
.
Instance Properties
menu
objects also have the following properties:
menu.items
A MenuItem[]
array containing the menu’s items.
An example of creating the application menu with the simple template API:
Render process
To create menus initiated by the renderer process, send the required information to the main process using IPC and have the main process display the menu on behalf of the renderer.
Below is an example of showing a menu when the user right clicks the page:
// renderer
window.addEventListener('contextmenu', (e) => {
e.preventDefault()
ipcRenderer.send('show-context-menu')
})
ipcRenderer.on('context-menu-command', (e, command) => {
// ...
})
ipcMain.on('show-context-menu', (event) => {
const template = [
{
click: () => { event.sender.send('context-menu-command', 'menu-item-1') }
},
{ type: 'separator' },
{ label: 'Menu Item 2', type: 'checkbox', checked: true }
]
const menu = Menu.buildFromTemplate(template)
menu.popup(BrowserWindow.fromWebContents(event.sender))
})
macOS has a completely different style of application menu from Windows and Linux. Here are some notes on making your app’s menu more native-like.
On macOS there are many system-defined standard menus, like the and
Windows
menus. To make your menu a standard menu, you should set your menu’s
role
to one of the following and Electron will recognize them and make them
become standard menus:
window
help
services
Standard Menu Item Actions
macOS has provided standard actions for some menu items, like About xxx
,
Hide xxx
, and Hide Others
. To set the action of a menu item to a standard
action, you should set the role
attribute of the menu item.
Main Menu’s Name
On macOS the label of the application menu’s first item is always your app’s
name, no matter what label you set. To change it, modify your app bundle’s
Info.plist
file. See
About Information Property List Files
for more information.
The of browser windows can set the menu of certain browser windows.
You can make use of before
, after
, beforeGroupContaining
, afterGroupContaining
and id
to control how the item will be placed when building a menu with Menu.buildFromTemplate
.
before
- Inserts this item before the item with the specified label. If the referenced item doesn’t exist the item will be inserted at the end of the menu. Also implies that the menu item in question should be placed in the same “group” as the item.after
- Inserts this item after the item with the specified label. If the referenced item doesn’t exist the item will be inserted at the end of the menu. Also implies that the menu item in question should be placed in the same “group” as the item.beforeGroupContaining
- Provides a means for a single context menu to declare the placement of their containing group before the containing group of the item with the specified label.afterGroupContaining
- 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 label.
By default, items will be inserted in the order they exist in the template unless one of the specified positioning keywords is used.
