  &lt;input matInput placeholder="Select Valid Till" name="GodownValidTill" [(ngModel)]="GodownValidTill" ngbDatepicker #d2="ngbDatepicker" required readonly&gt;
  &lt;mat-icon style="float:right;height:20px;width:20px;" (click)="d2.toggle()" svgIcon="calendar" title="Calendar"&gt;&lt;/mat-icon&gt;
