Identifier Usage
ngModelGroup #myTemplateVar="ngModelGroup"


This directive can only be used as a child of NgForm (within <form> tags).

Use this directive to validate a sub-group of your form separately from the rest of your form, or if some values in your domain model make more sense to consume together in a nested object.

Provide a name for the sub-group and it will become the key for the sub-group in the form's full value. If you need direct access, export the directive into a local template variable using ngModelGroup (ex: #myGroup="ngModelGroup").

Consuming controls in a grouping

The following example shows you how to combine controls together in a sub-group of the form.

import {Component} from '@angular/core';
import {NgForm} from '@angular/forms';

  selector: 'example-app',
  template: `
    <form #f="ngForm" (ngSubmit)="onSubmit(f)">
      <p *ngIf="nameCtrl.invalid">Name is invalid.</p>

      <div ngModelGroup="name" #nameCtrl="ngModelGroup">
        <input name="first" [ngModel]="name.first" minlength="2">
        <input name="middle" [ngModel]="name.middle" maxlength="2">
        <input name="last" [ngModel]="name.last" required>

      <input name="email" ngModel>

    <button (click)="setValue()">Set value</button>
export class NgModelGroupComp {
  name = {first: 'Nancy', middle: 'J', last: 'Drew'};

  onSubmit(f: NgForm) {
    console.log(f.value);  // {name: {first: 'Nancy', middle: 'J', last: 'Drew'}, email: ''}
    console.log(f.valid);  // true

  setValue() {
    this.name = {first: 'Bess', middle: 'S', last: 'Marvin'};
