The ngModelGroup directive allows you to group together related inputs so that you structure the object represented by the form in a useful and predictable way. ngModelGroup is often used in combination with fieldset as they mostly represent the same idea of “grouping together inputs.”
<form name="myForm2" #formRef2="ngForm" (ngSubmit)="onSubmit(formRef2.value)"> <fieldset ngModelGroup="login"> <legend>Login:</legend> Username: <input type="text" name="username" ngModel required> Password: <input type="password" name="password" ngModel requried> </fieldset> </form> <pre> form value: {{formRef2.value | json}} form valid: {{formRef2.valid | json}} </pre>
