The “Horizontal Gallery” and “Accordion” combination is malfunctioning.

Hey tchamp77,

Thank you for the inquiry,

This is to be expected, since the default behavior when clicking an inactive Horizontal Gallery item is to navigate or slide it to the center. This behavior overrides the anchoring to the Accordion items. Once the image is centered, the anchor should work without issue.

To override this behavior, you can try this script in the functions.php file:

<?php
add_action( 'wp_footer', 'ava_wp_footer_script_mod', 99 );

function ava_wp_footer_script_mod() {
    ?>
    <script>
    // override default horizontal gallery clicks behavior to open accordion and scroll to title
    (function($) {
        $(document).on('click', '.av-horizontal-gallery-slider a[href^="#toggle-id-"]', function(e) {
            e.preventDefault();
            e.stopImmediatePropagation();

            var targetId = $(this).attr('href').slice(1);

            setTimeout(function() {
                var $title = $('#toggle-toggle-' + targetId);
                var $wrap  = $('#' + targetId);

                if (!$title.length) return;

                if (!$wrap.hasClass('active_tc')) $title.trigger('click');

                setTimeout(function() {
                    $('html, body').animate({ scrollTop: $title.offset().top - 80 }, 500);
                }, 50);
            }, 50);
        });
    })(jQuery);
    </script>
    <?php
}

Best regards,
