title: How to create a modal popup that is compatible with Angular 4
body: <p>I want to be able to create a popup window which will load a certain Angular 4 component of mine when a radio button is selected. </p>
  
  <p>It seems that the methods listed in the answers to this <a href="https://stackoverflow.com/questions/35400811/how-to-use-codes-to-open-a-modal-in-angular-2">question</a> are only compatible with Angular 2.</p>
  
  <p>I am not sure where to begin and would appreciate any help!</p>
