title: Angular 2, set default value to select option
body: <p>I try to add a default value to an option. It will be like a kind of placeholder and I use <a href="https://stackoverflow.com/questions/5805059/how-do-i-make-a-placeholder-for-a-select-box">this method</a> to do it.
  In pure HTML it work, but if I try to use <code>*ngFor</code> of angular 2 attribute, it doesn't select anything.</p>
  
  <p>Here my code that I use in pure HTML:</p>
  
  <pre><code>  &lt;select name="select-html" id="select-html"&gt;
      &lt;option value="0" selected disabled&gt;Select Language&lt;/option&gt;
      &lt;option value="1"&gt;HTML&lt;/option&gt;
      &lt;option value="2"&gt;PHP&lt;/option&gt;
      &lt;option value="3"&gt;Javascript&lt;/option&gt;
    &lt;/select&gt;
  </code></pre>
  
  <p>And using Angular template:</p>
  
  <pre><code> &lt;select name="select" id="select" [(ngModel)]="selectLanguage"&gt;
      &lt;option *ngFor="let item of selectOption" 
        [selected]="item.value==0" 
        [disabled]="item.value==0"&gt;{{item.label}}&lt;/option&gt;
    &lt;/select&gt;
  </code></pre>
  
  <p>The class is</p>
  
  <pre><code>import {Component} from '@angular/core';
  
  @Component({
    moduleId: module.id,
    selector: 'app-form-select',
    templateUrl: 'default.component.html'
  })
  export class DefaultComponent {
    private selectOption: any;
    constructor() {
      this.selectOption = [
        {
          id: 1,
          label: "Select Language",
          value: 0
        }, {
          id: 2,
          label: "HTML 5",
          value: 1
        }, {
          id: 3,
          label: "PHP",
          value: 2
        }, {
          id: 4,
          label: "Javascript",
          value: 3
        }
      ]
    }
  }
  </code></pre>
  
  <p>I want <code>Select Language</code>to be selected as a default value. It's disabled but not selected.</p>
  
  <p>How can I select it as a default value?</p>
