Angular2: how bind to select multiple

Why all those complicate answers about simple question.

If you in advance have options which have to be selected, you can do it simply this way :

This code is good :

HTML

<select multiple [(ngModel)]="myModelProperty">
    <option *ngFor="#item of myOptions" [value]="item.value">{{item.name}}</option>
</select>

ANGULAR

myModelProperty: any;
myModelProperty = ['YOUR_VALUE', 'YOUR_VALUE'];

or if you have string, you can parse it

myModelProperty: any;
myModelProperty = string.split(',');

So, all you have to done is that [(ngModel)] from select tag, have to be initialized in angular part with some array of values which correspond to [value] from option tag

This will automatically select one or more options depends on values from array.
