Angular2: use [(ngModel)] with [ngModelOptions]=”{standalone: true}” to link to a reference to model’s property

I hope I understand your question, but the ng-model directive creates a two-way binding between the selected item in the control and the value of item.selectedVariant. This means that changing item.selectedVariant in JavaScript, or changing the value in the control, updates the other.
