What is causing the navigation menu to not appear on top in the vertical view on mobile devices in Webflow compared to tablet and horizontal mobile views?

TL;DR

Ensure the mobile nav has a high z-index (e.g., 9999) and correct positioning (Fixed or Absolute) on mobile portrait.
Check for overlapping elements, proper display settings (Display: Block or Flex), and interaction visibility specific to the mobile breakpoint.

Your navigation menu not appearing on top in vertical mobile view is typically caused by z-index conflicts or positioning issues that behave differently at certain breakpoints.

Select your nav wrapper, menu button, and open menu container.
In the Style panel, ensure the nav or menu has a higher z-index than overlapping sections (e.g., popups, banners, hero sections).
Try setting the mobile nav menu’s z-index to 9999 as a test on the mobile portrait breakpoint only.

2. Confirm Positioning is Set Correctly

The mobile nav should have Position: Fixed or Absolute with appropriate top/left/right/bottom values on smaller breakpoints.
If set to Relative or Static, it may get pushed below other content on mobile portrait view.

3. Check if Other Elements Are Overlapping

Divs like hero sections, overlays, or custom components may be covering the nav due to improper positioning or stacking order.
Use Webflow’s Preview mode and Element Inspector to see what element is layered above the nav in mobile portrait.

4. Verify Display Settings at Each Breakpoint

Select your dropdown menu or mobile menu (typically a div block triggered by the hamburger icon).
Ensure it is set to Display: Block or Flex when open, especially on mobile portrait. Sometimes menus don’t auto-display if visibility isn’t configured per breakpoint.

5. Recheck Interactions and Animations

Menu open/close actions using interactions may not be working correctly just on vertical mobile view.
Test to see if an interaction is set to affect only a certain breakpoint or is toggling visibility improperly (e.g., hiding instead of sliding in).

Summary

The mobile nav not displaying on top in vertical view is likely due to a z-index or positioning conflict, or display settings that don’t carry over correctly to the smallest breakpoint. Focus on making sure the nav menu has a high z-index, correct positioning, and is set to display on mobile portrait specifically.
