Navigation List data-state help

[sushantgwr87]

I am using this Radix-ui/NavigationMenu with Next.js

I created Navbar where content shows on clicking the Trigger. Used way describe here #1381.

I used NavigationMenu.List for nav design with background color.

Problem is I want to change the background color of this List when viewport shows or when data-state=open but List does not has this data-state attribute and I can't find a way around this.
