Use a binding for the value in your template.
value="{{ option.id }}"
should be
[value]="option.id"
And in your selected value use ngModel
instead of value
.
<mat-select [(value)]="selected2">
should be
<mat-select [(ngModel)]="selected2">
Complete code:
<div>
<mat-select [(ngModel)]="selected2">
<mat-option *ngFor="let option of options2" [value]="option.id">{{ option.name }}</mat-option>
</mat-select>
</div>
On a side note as of version 2.0.0-beta.12 the material select now accepts a mat-form-field
element as the parent element so it is consistent with the other material input controls. Replace the div
element with mat-form-field
element after you upgrade.
<mat-form-field>
<mat-select [(ngModel)]="selected2">
<mat-option *ngFor="let option of options2" [value]="option.id">{{ option.name }}</mat-option>
</mat-select>
</mat-form-field>
