Hiding block title when customizing I would like to hide the block title when customizing a block, but I didn't find any solution on the internet, Can you please help me?

function custom_theme(&amp;$existing, $type, $theme, $path) {

  $hooks['user_login_block'] = array(
    'template' =&gt; 'templates/user_login',
    'render element' =&gt; 'form',
    // other theme registration code...
  );
  return $hooks;
}
You can do it easily directly in the configuration page of block by adding &lt;none&gt; in the title field setting.
