title: Angular CDK: How to set Inputs in a ComponentPortal
body: <p>I would like to use the new <a href="https://material.angular.io/cdk/portal/overview" rel="noreferrer">Portal</a> from material CDK to inject dynamic content in multiple part of a form.</p>
  
  <p>I have a complex form structure and the goal is to have a form that specify multiple place where sub components could (or not) inject templates. </p>
  
  <p>Maybe the CDK Portal is not the best solution for this?</p>
  
  <p>I tried something but I am sure it is not the way of doing:

  <p>I tried also with <code>new ComponentPortal(MyPortalComponent)</code> but how can we set Inputs on it ? Usually is something like <code>componentRef.component.instance.myInput</code></p>
