How To Make The Dropdown-full Screen In Relume Navbar 4

A community member is building a site using the Relume Navbar 4 component and is having trouble making the dropdown cover the entire screen with a dark green color as shown in a video. They have tried adjusting the div positioning but cannot find a solution. Another community member suggests that this will likely require custom CSS and offers to take a look at the published site. The community member shares the published URL and a video is recorded to help. After making some minor tweaks, the community member is able to get a working solution, but is not fully satisfied with the nav links being "masked off" when the nav closes, and believes they can fix this with some animation on the nav links.
