constructor(public navCtrl: NavController, public navParams: NavParams) {
// If we navigated to this page, we will have an item available as a nav param
this.selectedItem = navParams.get('item');

// Let's populate this page with some filler content for funzies
this.icons = ['flask', 'wifi', 'beer', 'football', 'basketball', 'paper-plane',
'american-football', 'boat', 'bluetooth', 'build'];

this.items = [];
for (let i = 1; i < 11; i++) {
this.items.push({
title: 'Item ' + i,
note: 'This is item #' + i,
icon: this.icons[Math.floor(Math.random() * this.icons.length)]
