From within your child theme you may want to add or edit an Advanced Layout Builder element. To do so, first add the following function to your child theme’s functions.php:

add_filter('avia_load_shortcodes', 'avia_include_shortcode_template', 15, 1);
function avia_include_shortcode_template($paths)
	$template_url = get_stylesheet_directory();
    	array_unshift($paths, $template_url.'/shortcodes/');

	return $paths;

Now add a new folder in your child theme directory called shortcodes. If you copy an element from enfold>config-templatebuilder>avia-shortcodes to this folder it will replace the one in the parent and be used instead. You can also add new ones using the other shortcode elements as examples.
