How can I validate nested form groups in Angular?

You can validate nested form groups in Angular by using the FormGroup and FormArray classes. You can define validators for each control within the nested structure.

Can you show me an example of how to set this up?

Sure! First, create a FormGroup for the parent form, then add a FormArray for the nested groups. Each FormGroup inside the FormArray can have its own validators.

What if I want to add dynamic form controls to the nested groups?

You can use the push method of FormArray to add new FormGroup instances dynamically. Just ensure to set up the validators for the new controls as well.

How do I display validation errors for these nested controls?

You can check the validity of each control and display error messages conditionally in your template using Angular's reactive forms features.
