title: How can I make reCAPTCHA a required field?
body: <p>I'm using Google reCAPTCHA and have been able to add the CAPTCHA component to my page inside a form. But when I submit the form there's no validation taking place to check if the CAPTCHA has been solved.</p>
  
  <p>How do I validate that the CAPTCHA component has been solved when submitting my form? Or, in other words, how do I make my CAPTCHA component required?</p>
