Why are the menu dropdowns not working in Chrome after updating to Windows 10 on both a PC and Mac using the same version of Chrome?

TL;DR
  • Check Chrome's Console for JavaScript errors that may prevent dropdown functionality.
  • Verify dropdown behavior settings in Webflow Designer and test in Preview Mode.
  • Clear Chrome cache, disable extensions, and test in Incognito and other browsers.
  • Ensure custom animations or CSS (e.g., pointer-events: none) aren’t interfering.
  • Re-publish the Webflow site to apply updates and fixes.

Dropdown menus not working in Chrome after a Windows 10 update may be caused by browser compatibility issues, OS-level changes impacting input events, or JavaScript errors in your Webflow project.

1. Check for Console Errors in Chrome

  • Open Developer Tools (right-click on the page → Inspect → go to Console tab).
  • Look for any JavaScript errors that could prevent the dropdown interaction scripts from executing.
  • Common issues include conflicts with custom code or libraries not loading properly.

2. Confirm Webflow's Dropdown Settings

  • In Webflow Designer, select the Dropdown Trigger element.
  • Ensure the dropdown is set to open on click or hover depending on your intended behavior.
  • Test the dropdowns in Preview Mode to confirm they are functioning inside Webflow.

3. Clear Browser Cache and Disable Extensions

  • Clear Chrome's cache and cookies, then refresh the page.
  • Temporarily disable all browser extensions, especially ones that block scripts or modify CSS (e.g., ad blockers, script blockers).

4. Verify Animation or Interaction Conflicts

  • If dropdowns use custom interactions, ensure any animations are not preventing pointer events or visibility.
  • Check if any initial states are causing the dropdowns to be hidden or display: none.

5. Test in Incognito and Other Browsers

  • Open the site in Chrome Incognito Mode to rule out caching or extensions.
  • Test in Edge or Firefox to see if the issue is browser-specific.
  • If dropdowns work elsewhere but not in Chrome, the browser may be misinterpreting input events due to OS updates.

6. Re-Publish the Webflow Site

  • Go to Project Settings → Publish tab, then click Publish to selected domains.
  • This ensures any required JavaScript or style changes are updated on the live site.

7. Disable Pointer Event Overrides

  • Review any custom CSS that might block dropdown functionality (e.g., pointer-events: none on a parent container).
  • These styles could behave differently after a browser or OS update.

Summary

The dropdown issue in Chrome after a Windows 10 update is likely caused by JavaScript errors, custom code conflicts, CSS pointer-event overrides, or browser extensions. Use Webflow Preview mode, Chrome DevTools, and browser isolation steps to pinpoint the source and ensure your dropdown settings and interactions are configured correctly.
