If you're having issues with your website still scrolling when you open your navigation menu, this snippet will stop your headaches.

Go into your project settings and add this code to the </body> section of your custom code:

   // Stop body scroll when mobile menu is open
   const body = document.body;
   function letBodyScroll(bool) {
       if (bool) {
               body.style.overflow = 'hidden';
       } else {
           body.style.overflow = 'auto';
  const targetNode = document.querySelector('.w-nav-button');
   const config = { attributes: true, childList: false, subtree: false };
   const callback = function (mutationsList, observer) {
       for (let i = 0; i < mutationsList.length; i++) {
           if (mutationsList[i].type === 'attributes') {
               const menuIsOpen = mutationsList[i].target.classList.contains('w--open');
   const observer = new MutationObserver(callback);
   observer.observe(targetNode, config);
