Hello,
Try to add the following code snippet to the Custom JS area on the document ready in Theme Settings to fix this issue.
jQuery('.wc-tabs-wrapper .woodmart-accordion-title').click(function (e) {
e.stopPropagation();
e.preventDefault();
var $this = jQuery(this),
$panel = $this.siblings('.woocommerce-Tabs-panel');
if ($this.hasClass('active')) {
$this.removeClass('active');
$panel.stop().slideUp(300);
} else {
$this.addClass('active');
$panel.stop().slideDown(300);
}
jQuery(window).resize();
jQuery(document).trigger('wood-images-loaded');
});
When you click the next tab, the previous one would remain open with this code. If you want the code where all the tabs are open, let us know, we shall provide, however, we do not guarantee it would be stable.
Kind Regards
