Using ngModel to Select something with Angular. With disabled options, callback and default value.

angular-select.component.html

<select [ngModel]="vm.selectedThing"
  (ngModelChange)="onSelectThing($event)">
  <option [value]="null">-</option>
    <option *ngFor="let thing of vm.things"
      [value]="thing.id"
      [disabled]="thing.isDisabled">
    {{thing.name}}
  </option>
</select>

angular-select.component.ts

// Standard Angular component. Make sure you import FormsModule into your Module!
class AngularSelectComponent {  
  vm: { selectedThing : any, things:any[] } = { 
    selectedThing : null, 
    things:[{
      name:"thing-1",
      id:1,
      isDisabled:false
     },
     {
      name:"thing-2",
      id:2,
      isDisabled:false
     }]
  };
  constructor(){
    setTimeout(function(){
      this.vm.selectedThing = this.vm.things[1].id;
    }.bind(this), 2000);
  }
  onSelectThing($event) {
    console.log($event);
  }
}
