Hi there,
I’m using the Signify Blocks Pro theme with the Site Editor, and I’ve run into an issue where the mobile navigation menu (dropdown) appears behind page content — but only on certain pages.

Details:
The issue occurs on three specific pages:

/my-account
/my-profile
/my-sessions

These are logged-in-only pages built using WP User Manager shortcodes.

On those pages, when opening the mobile menu, the dropdown renders underneath the page content.

Specifically:

Text from the menu does not appear at all

Only graphics (like icons or buttons) from the menu show up, and they are partially obstructed by the page’s existing content.

The same menu works correctly on all other pages (logged out or public-facing).

I’ve placed the menu in a custom Thin Header template part using the Full Site Editor.

I’ve already tried increasing z-index and using position: fixed on the menu container, as well as lowering z-index on the .wpum-account, .wpum-content, and related containers — no change.

Browser cache has been cleared, and no caching plugin is active.

This behavior is consistent across both Chrome and Edge on mobile and tablet.

❓ Questions:
Is this a known behavior with how the theme renders navigation inside block-based template parts?

Are there any theme-specific wrappers or CSS resets that may be interfering with stacking context?

Is there a recommended way to make the mobile menu reliably overlay all content, including WP User Manager areas?

I really like the theme and just want to resolve this one display issue that’s affecting mobile usability.
Thank you so much for any guidance you can offer!
