menu
The Menu
class is used to create native menus that can be used as
application menus and context menus. Each menu consists of multiple menu
items, and each menu item can have a submenu.
Below is an example of creating a menu dynamically in a web page by using the remote module, and showing it when the user right clicks the page:
<!-- index.html -->
<script>
var remote = require('remote');
var Menu = remote.require('menu');
var MenuItem = remote.require('menu-item');
var menu = new Menu();
menu.append(new MenuItem({ label: 'MenuItem1', click: function() { console.log('item 1 clicked'); } }));
menu.append(new MenuItem({ type: 'separator' }));
menu.append(new MenuItem({ label: 'MenuItem2', type: 'checkbox', checked: true }));
window.addEventListener('contextmenu', function (e) {
e.preventDefault();
menu.popup(remote.getCurrentWindow());
}, false);
</script>
Another example of creating the application menu with the simple template API:
// main.js
var template = [
{
label: 'Electron',
submenu: [
{
label: 'About Electron',
selector: 'orderFrontStandardAboutPanel:'
},
{
type: 'separator'
},
{
label: 'Services',
submenu: []
},
{
type: 'separator'
},
{
label: 'Hide Electron',
accelerator: 'Command+H',
selector: 'hide:'
},
{
label: 'Hide Others',
accelerator: 'Command+Shift+H',
selector: 'hideOtherApplications:'
},
{
label: 'Show All',
selector: 'unhideAllApplications:'
},
{
type: 'separator'
},
{
label: 'Quit',
accelerator: 'Command+Q',
click: function() { app.quit(); }
},
]
},
{
label: 'Edit',
submenu: [
{
label: 'Undo',
accelerator: 'Command+Z',
selector: 'undo:'
},
{
label: 'Redo',
accelerator: 'Shift+Command+Z',
selector: 'redo:'
},
{
type: 'separator'
},
{
label: 'Cut',
accelerator: 'Command+X',
selector: 'cut:'
},
{
label: 'Copy',
accelerator: 'Command+C',
selector: 'copy:'
},
{
label: 'Paste',
accelerator: 'Command+V',
selector: 'paste:'
},
{
label: 'Select All',
accelerator: 'Command+A',
selector: 'selectAll:'
},
]
},
{
label: 'View',
submenu: [
{
label: 'Reload',
accelerator: 'Command+R',
click: function() { BrowserWindow.getFocusedWindow().reloadIgnoringCache(); }
},
{
label: 'Toggle DevTools',
accelerator: 'Alt+Command+I',
click: function() { BrowserWindow.getFocusedWindow().toggleDevTools(); }
},
]
},
{
label: 'Window',
submenu: [
{
label: 'Minimize',
accelerator: 'Command+M',
selector: 'performMiniaturize:'
},
{
label: 'Close',
accelerator: 'Command+W',
selector: 'performClose:'
},
{
type: 'separator'
},
{
label: 'Bring All to Front',
selector: 'arrangeInFront:'
},
]
},
{
label: 'Help',
submenu: []
},
];
menu = Menu.buildFromTemplate(template);
Menu.setApplicationMenu(menu); // Must be called within app.on('ready', function(){ ... });

Notes on OS X application menu
OS X has a completely different style of application menu from Windows and Linux, and here are some notes on making your app's menu more native-like.
Standard menus
On OS X there are many system defined standard menus, like the Services
and
Windows
menus. To make your menu a standard menu, you can just set your menu's
label to one of followings, and Electron will recognize them and make them
become standard menus:
Window
Help
Services
Standard menu item actions
OS X has provided standard actions for some menu items (which are called
selector
s), like About xxx
, Hide xxx
, and Hide Others
. To set the action
of a menu item to a standard action, you can set the selector
attribute of the
menu item.
Main menu's name
On OS X the label of application menu's first item is always your app's name,
no matter what label you set. To change it you have to change your app's name
by modifying your app bundle's Info.plist
file. See
About Information Property List Files
for more.
