Hello,
In our theme not such possibility by default, so please note that such question requests additional customization which is beyond our basic support scope.
You may add this code in function.php file of your child theme https://prnt.sc/gfb65z:
wp_enqueue_script('child-theme', get_stylesheet_directory_uri().'/etheme-child.js',array(),false,true);
then create etheme-child.js file in your child theme and add this code:
jQuery(document).ready(function(){
jQuery('.icon-reorder').on('click', function(event) {
jQuery('li.menu-item-has-children').addClass('over').find('.sub-menu').slideDown(0);
});
});
Regards
