Top Navigation Bar

Hello,

I want to preface this by saying I am not a coder.

I have seen a navigation menu (top bar, header bar, whatever you want to call it) that I really like. I typically import a theme in generatepress (I use elementor) to get the structure I like, and then I tweak as needed.

The site I saw that had an awesome nav bar is: https://clickflame.com/

I want to figure out how to make that happen, but I dont know where to go (or what to do). I have used the Jupiter theme in the past, and it had a header builder, but there is nothing like that in Generatepress. The site above was built with underscores.me, so I don't know if I should used that as my child theme? I usually just create a child theme from a simple generator online.

Any help would be greatly appreciated.

Thanks
