How can I create nested form groups in Angular?

To create nested form groups in Angular, you can use the FormGroup and FormArray classes from Reactive Forms.

Can you show me a code example?

Sure! Here's a simple example:

this.form = this.fb.group({
  user: this.fb.group({
    name: [''],
    address: this.fb.group({
      street: [''],
      city: ['']
    })
  })
});

How do I access the values of these nested groups?

You can access the values using the get method:

const street = this.form.get('user.address.street').value;

What if I want to add more fields dynamically?

You can use FormArray to manage dynamic fields. You can push new FormGroup instances to the FormArray.
