title: Drupal 8 - Repeatable Form Fields
body: <p>I am looking to build a module in Drupal 8 after having used Joomla. The issue I'm having is that I can't seem to find a way to configure additional fields where required. Similar to <a href="https://docs.joomla.org/Repeatable_form_field_type" rel="nofollow">this method</a> in Joomla if possible so that I can add more of the same fields e.g multiple contact number boxes. </p>
