How can I mimic Chanel's website header design for my online store?

Hello, Thank you for your help.

I would like to use the same header design as on the Chanel website.

This includes a dropdown menu that disappears when you scroll down and reappears when you scroll up, and lines above and below the header. 

Chanel homepage: https://www.chanel.com/us/
My store: https://guri.store/

 Thank you!

Hi, @Guribabo 

It can be implemented, but the theme source code needs to be modified. This is not a simple process. If needed, I can help you modify it.
