If you want to use it as menu, it’s better to replace 42 line with this:
<ons-splitter-side collapse=“collapse” swipeable=“true” [page]=“sidePage” side=“left” width=“200px” style=“border-right: 1px solid #ccc”>

@shivavelingker: To make it works you should remove lines 76,77,81 and left only this code in AppComponent’s template:
<ons-tabbar>
<ons-tab label=“Page1” icon=“ion-home” [page]=“tab1” active></ons-tab>
<ons-tab label=“Page2” icon=“ion-ios-browsers” [page]=“tab2”></ons-tab>
<ons-tab label=“Page3” icon=“ion-ios-search” [page]=“tab3”></ons-tab>
</ons-tabbar>
