Angular

Nested FormGroups

-In a large complex application you might have a form with multiple sub-groups

form = new FormGroup({
	account: new FormGroup({
		username: new FormControl(),
		password: new FormControl()
	})
})

get username(){
	return this.form.get('account.username');
}

<div formGroupName="account">
	<div>
		<input formControlName="username">
	</div>
</div>
