title: Pass Angular Reactive FormControls to Children Components
body: <p>I have a parent component where I want to create and store my Reactive Form. There will be multiple Form Group instances in a Form Array. I want to pass the Form Controls from each Form Group to a Child Component but am having trouble figuring out how to do this.</p>
  
  <p>Here's a <a href="https://stackblitz.com/edit/angular-tjbj6o" rel="noreferrer">Stackblitz</a> demonstrating what I would like to do. Also, some fields will only apply to certain 'makes' of cars which is why i have the following line in my html:</p>
  
  <pre><code>&lt;input type="text" *ngIf="car.make != 'ford'" formControlName="model"&gt;
  </code></pre>
  
  <p>I would like to move the 'Details' Form Group fields into the 'details-fields' child component but when I try to do that, it tells me that I don't have a Form Group instance so I know the parent Form Group is not registering in the child component. Any help is much appreciated.</p>
