title: Angular 10, 3 levels of nested from group with array
body: <p>First: This is the project link: <a href="https://stackblitz.com/edit/angular-kmadq6" rel="nofollow noreferrer">https://stackblitz.com/edit/angular-kmadq6</a></p>
  <p>So.. I have the testForm with 3 levels of formGroup, and the last formGroup is an array of formGroups.
  (File app.component.ts)..</p>
  <p>Thus, i want to click on checkbox and enable the price field.</p>
  <p>I didn't know how to get the price control from array of this form group.</p>
  <p>I know that i can disable it by using [attr.disable]=&quot;variable&quot; but is it mixind TemplateDrivenForm with ReactiveForm, but, if don't have any way to disable it from ReactiveForm way, i'll use this.</p>
  <p>Thank you!</p>
