generate_smooth_scroll_elements

The generate_smooth_scroll_elements allow you to initiate smooth scroll on other element classes instead of just ones with the smooth-scroll class.

Use the following PHP snippet to apply smooth scroll to all hash links:

add_filter( 'generate_smooth_scroll_elements', function( $elements ) {
  $elements[] = 'a[href*="#"]';
  
  return $elements;
} );
