Open menu from a link

Hey arasaac,
You could try this script, I tested it with a slideshow button and it worked, so you will need to adjust it to use the class you are going to use.
Try adding this code to the end of your functions.php file in Appearance ▸ Editor:

function custom_script() { ?>
    <script>
(function($){
    $('a.avia-slideshow-button').on('click', function(e) {
        e.preventDefault();
        $('.av-burger-menu-main a').trigger('click');
    });
})(jQuery);
</script>
    <?php
}
add_action('wp_footer', 'custom_script');

If you need help adjusting this then include an admin login in the Private Content area and a link to a text page with the element you want to use as the trigger.

Best regards,
Mike
