In this tutorial, we will see how to create,

1.Nested Form Group
2. How to Access controls in Nested Form Group

In the previous tutorial, we have seen how to create a simple formgroup

eg :
userprofileForm = new FormGroup({
firstName: new FormControl(''),
lastName: new FormControl(''),
age: new FormControl(''),
email:new FormControl(''),
});



So we will have a nested formgroup named "address"

userprofileForm = new FormGroup({
firstName: new FormControl(''),
lastName: new FormControl(''),
age: new FormControl(''),
email:new FormControl(''),

,
address: new FormGroup({
address1: new FormControl(''),
address2: new FormControl(''),
state: new FormControl(''),
zip: new FormControl('')
})
});


So here we will define the controls in same way in html:
How to Access controls in Nested Form Group :

We can access the formcontrol in the nested FormGroup using :

this.userprofileForm.get(['address','address1']).value

Here userprofileForm is the root formgroup. In the Get method, we will pass the name of the nested formgroup named
'address' and the formcontrol in that formgroup named 'address1'.

We can also do the same thing using,

this.userprofileForm.get('address').get('address2').value
