Nested Forms

Introduction

Nested forms use FormGroup within FormGroup to create hierarchical form structures.

Example

this.userForm = this.fb.group({
  personal: this.fb.group({
    firstName: [''],
    lastName: [''],
    address: this.fb.group({
      street: [''],
      city: [''],
      zip: ['']
    })
  }),
  preferences: this.fb.group({
    newsletter: [false],
    theme: ['light']
  })
});

Summary

Nested forms organize complex data into logical hierarchies.”
