title: Toggle div with Angular 6
body: <p>I'm new to Angular and want to start with something simple to learn.</p>
  
  <p>I'm currently developing a form and have divs which I need to toggle upon user selection. Do I need to create Angular 6 component to create such a toggle function?</p>
  
  <p>How can I do the toggle - whether with component or without (if possible)?</p>
  
  <p>Thanks</p>
