Meteorbox - function for creating sidebar menu

createSidebarMenu.js

// With this function you can build sidebar menus
// dynamically just from your API.
// You just construct your menu object like this:

//   {
//     name: 'Main menu', // This is just a name to identify your menu (useful if you got more than one)
//     menuItems: [ // main menu items
//       {
//         title: 'Dashboard',
//         link: null,
//         children: [ // submenu items
//           {
//             title: 'Submenu 1',
//             link: '#',
//             children: [],
//             icon: 'sidebar-sub-link fa fa-circle-thin', // FontAwesome icon className
//           },
//           {
//             title: 'Submenu 2',
//             link: '#',
//             children: [],
//             icon: 'sidebar-sub-link fa fa-circle-thin',
//           },
//           ... // rest of your submenu items
//         ],
//         icon: 'fa fa-signal fa-fw',
//         notificationCount: null
//       },
//       ... // rest of your main menu items
//     ]
//   };
