Apologies for the inconvenience.

Unfortunately, there is no built-in feature for swipe navigation between tabs in this component at the moment. However, a similar user experience can be achieved using a small custom JavaScript enhancement.

Please add the following JS code to your Template Options → Custom Code → Custom JS section:

(function ($) {
  "use strict";

  function initTabSwipe() {

    $('.sppb-addon-tab').each(function () {

      const $container = $(this);
      const $tabContent = $container.find('.sppb-tab-content').get(0);
      const $tabLinks = $container.find('.sppb-nav li a');

      if (!$tabContent || $tabContent.dataset.swipeInit) return;

      $tabContent.dataset.swipeInit = "true";

      let startX = 0;
      let endX = 0;

      $tabContent.addEventListener('touchstart', function (e) {
        startX = e.changedTouches[0].screenX;
      }, { passive: true });

      $tabContent.addEventListener('touchend', function (e) {
        endX = e.changedTouches[0].screenX;

        const diff = startX - endX;
        const threshold = 60;

        if (Math.abs(diff) < threshold) return;

        let activeIndex = 0;

        $tabLinks.each(function (i) {
          if ($(this).parent().hasClass('active')) {
            activeIndex = i;
          }
        });

        // swipe left → next tab
        if (diff > 0 && activeIndex < $tabLinks.length - 1) {
          $tabLinks.eq(activeIndex + 1).trigger('click');
        }

        // swipe right → previous tab
        if (diff < 0 && activeIndex > 0) {
          $tabLinks.eq(activeIndex - 1).trigger('click');
        }

      }, { passive: true });

    });

  }

  // Init on load
  $(document).ready(function () {
    initTabSwipe();
  });

  // Optional: re-init if SPPB loads dynamically (AJAX / builder edits)
  $(window).on('load', function () {
    initTabSwipe();
  });

})(jQuery);

After applying this change, please clear both your Joomla cache and your browser cache to ensure the script is loaded correctly.

This will enable left/right swipe gestures on mobile devices, providing a much smoother tab navigation experience similar to native mobile interfaces.
