document.addEventListener("DOMContentLoaded", function () {
      const scrollImages = document.querySelector(".scroll-images");
      const scrollLength = scrollImages.scrollWidth - scrollImages.clientWidth;
      const leftButton = document.querySelector(".left");
      const rightButton = document.querySelector(".right");

      function checkScroll() {
        const currentScroll = scrollImages.scrollLeft;
        if (currentScroll === 0) {
          leftButton.setAttribute("disabled", "true");
          rightButton.removeAttribute("disabled");
        } else if (currentScroll === scrollLength) {
          rightButton.setAttribute("disabled", "true");
          leftButton.removeAttribute("disabled");
        } else {
          leftButton.removeAttribute("disabled");
          rightButton.removeAttribute("disabled");

when the site is LTR (left to right) the menu is working 100% good .
but in RTL direction it is not working good .
i think that this code force the menu scroll from the left :
if (currentScroll === 0)

how to force the menu to detect rtl or start scroll from right if the site is rtl direction ?
