By default when you use header image the menu will appear below the image. But in our demo we have used the slider image so the menu is appearing above the image. You can use slider instead. Else you have to modify the code through child theme if you want to achieve this with header image
Thanks Guys I needed this info. I have one additional question. Rabin you said the demo was used with the slider image. How do I access this “slider image”? Is it an additional plugin?
