So, I'm building a softare using electron. Now I can add menu in the software from a template 

var menu = Menu.buildFromTemplate([
  {
      label: 'Menu',
      submenu: [
          {label:'open'},
          {label:'save'},
          {label:'Exit'}
      ]
  }
])
Menu.setApplicationMenu(menu);

But how do I modify a single menu item. For example, say, the save menu is disabled by default and activated after the open is clicked. Also say after clicking open a new menu edit appears. I can create the complete new template in full and just change the previous template with the new. But thats a bad way and can't be a practical solution when I'm using several menus with several submenus. So can I modify just one single menu item of my choice?

You can get the menu items using:

import { Menu } from 'electron';

Menu.getApplicationMenu().items // all the items
Menu.getApplicationMenu().getMenuItemById('MENU_ITEM_ID') // get a single item by its id

After that you have several properties on the single menu item as:

- checked
- enabled
- visible
- label
- click

And you can customize your behavior as you want to.

Tested with electron 3.0.5, before the 27 Sep 2017 the method getMenuItemById was not there and you had to loop over all the items.
