Hi there,
as far as I understand the question (`import {Component} from 'angular2/core'`), it is clearly about angular 2.

Hi Sanjit,

did you already check out the Angular 2 tutorial on angular.io? They cover a lot of typical examples and they explain things very clearly.

In this case, take a look at the Master/Detail part[^] and search for "Hide the empty detail with ngIf"

This code only shows a div, if the selectedHero property is set.

HTML

<!-- template -->
<div *ngIf="selectedHero"></div>

JavaScript

// controller
onSelect(hero: Hero) { this.selectedHero = hero; }

Hope this helps. If you have further questions, feel free to ask.
