<ion-menu [content]=“content” side=“left”>

<ion-nav [root]=“HomePage” id=“nav” #content>
(Home is the where menu will open, i don’t know it its right, I tryed rootPage - example)

and In Home Header

  <ion-toolbar color="primary">
    <ion-buttons right><button ion-button menuToggle><ion-icon name="md-menu"></ion-icon></button></ion-buttons>
