<div *ngFor="let option of options">
        <div class="radio">
            <input type="radio"
               name="radio"
               id="radio-{{option.id}}"
               [(ngModel)]="value"
               [value]="option.value"
               required

               /> 
        <label for="radio-{{option.id}}">{{option.id}}
        </label> 
    </div>
  </div>

  <div *ngIf="f.submitted && !f.valid">Please select</div>
