If there are tabs that don’t have any content or rely on a shortcode that doesn’t render any content, you can hide those tabs dynamically using the code below:

// PowerPack Advanced Tabs: Do not render tabs if the tab content is empty.
add_filter( 'pp_tabs_items', function( $items, $settings ) {
  foreach ( $items as $key => $item ) {
    $content = do_shortcode( $item->content );
    $content = preg_replace( '/<p><\/p>/', '', $content );
    if ( empty( trim( $content ) ) ) {
       unset( $items[ $key ] );
    }
  }
  return array_values( $items );
}, 10, 2 );

You just need to insert this code into your current child theme’s functions.php file.
