More background options for Burger Overlay (transparent overlay + custom background image)

Description:

Currently, the Burger Overlay (the menu that opens when clicking the hamburger icon) only allows a solid background color with customizable color and typography settings.

This limits the visual flexibility of the overlay and can interrupt the overall design flow of the page.

Suggested solution:

Add more background options for the Burger Overlay, including:

A transparent overlay option, allowing the current page background to remain visible behind the menu

The option to upload and use a custom background image for the overlay

This would allow the menu links to appear directly over the existing page background or over a specifically designed background image.

Benefit:

This would create a more seamless and visually consistent user experience, while offering greater design freedom and better integration of the navigation menu into the overall page aesthetic.
