title: Drupal 8: Showing the child taxonomy terms where the parent taxonomy term is displayed
body: <p>I am currently displaying a taxonomy entity reference field. This is the full entity, with all fields. Now, all the fields of this term are displayed on the page. But the underlying child terms are not. Is there any way to show the child terms alongside with the rest of the parent term fields on to the page? Thanks in advance.</p>
