title: Is there elseIf in Angular 4
body: <p>I have a number of statements</p>
  
  <pre><code>&lt;ng-template [ngIf]="xyz== 1"&gt;First&lt;/ng-template&gt;
  &lt;ng-template [ngIf]="pqr == 2"&gt;Second&lt;/ng-template&gt;
  &lt;ng-template [ngIf]="abc == 3"&gt;Third&lt;/ng-template&gt;
  </code></pre>
  
  <p>Multiple conditions in above statement can be true.</p>
  
  <p>But what i want is, first check for first statement if true then display and leave the rest</p>
  
  <p>If false, then check for second and so on</p>
  
  <p>how to achieve this?</p>
