How can I prevent the background from scrolling when it is overlayed with a drop-down menu in Webflow? The suggested solution of using webflow.push as a function did not work and overflow-hidden and position-fixed also did not take any action. The page is completely covered with .w-nav-overlay, which causes the overlay to draw the height larger than the page, making it impossible to stop the scrolling. Can someone please help me with this issue?

You're trying to prevent background scrolling when a full-page .w-nav-overlay dropdown is open, but standard solutions like overflow: hidden on body/html aren't working due to the overlay affecting page height.

1. Understand the Origin of the Scroll

• .w-nav-overlay often gets appended to the body by Webflow’s native navbar component.
• When it opens, it may extend beyond viewport height, causing the browser to allow scrolling.
• Standard overflow: hidden won't work if the overlay adds to scroll height instead of floating absolutely.

2. Use Body Fixed Position Method

Instead of just using overflow: hidden, try the following combination when the dropdown is open:

• Set body to position: fixed, width: 100%, and preserve scrollY offset.
• In Webflow, use custom code in the Page Settings > Footer custom code or inside an Embed element:

Add this script:

<script>  let scrollTop = 0;  const navButton = document.querySelector('.w-nav-button');  const navOverlay = document.querySelector('.w-nav-overlay');  const disableScroll = () => {    scrollTop = window.scrollY;    document.body.style.position = 'fixed';    document.body.style.width = '100%';    document.body.style.top = `-${scrollTop}px`;  };  const enableScroll = () => {    document.body.style.position = '';    document.body.style.top = '';    document.body.style.width = '';    window.scrollTo(0, scrollTop);  };  const observer = new MutationObserver(() => {    const isOpen = navOverlay && getComputedStyle(navOverlay).display !== 'none';    isOpen ? disableScroll() : enableScroll();  });  if (navOverlay) {    observer.observe(navOverlay, { attributes: true, attributeFilter: ['style'] });  }</script>

• This script detects changes to .w-nav-overlay and disables/enables background scroll accordingly.
• It also prevents content jumping by restoring scroll position when re-enabling scroll.

3. Adjust .w-nav-overlay Positioning if Needed

If .w-nav-overlay is pushing page height:

• Set .w-nav-overlay to position: fixed, top: 0, left: 0, height: 100vh, width: 100%.
• This ensures it doesn't contribute to total document height.

You can apply this manually in Webflow:

• Select .w-nav-overlay in the Navigator.
• Set position to Fixed, full screen.
• Ensure z-index is high enough to cover all content.

4. Avoid webflow.push for Scroll Lock

• The Webflow.push method is deprecated or limited to specific integrations (e.g., custom events).
• It's unreliable for general DOM manipulation like scroll locking.

Summary

Set the .w-nav-overlay to position: fixed and use JavaScript to toggle body { position: fixed; } when the menu opens. This approach prevents background scroll regardless of overlay height and avoids Webflow's default behaviors that break standard overflow: hidden.
