title: How to use FontAwesome with simple_form
body: <p>this my first post!</p>
  
  <p>I want to use a fontawesome icon :
  <code>&lt;i class="fas fa-star"&gt;&lt;/i&gt;</code></p>
  
  <p>in a simple_form form.
  <code>&lt;%= f.input :rating, collection: 0..5 %&gt;</code></p>
  
  <p>What is the best way to do this?

  Thanks</p>
