Hello,
You’re welcome.
Sorry, but full width menu feature is available for Legenda theme only.
As I misunderstood you concerning the menu question you may remove the code in custom.css file.
You can upload screenshots to some image storage and then provide us with the links to images.
Please show us what you want to do with categories on the Shop page to avoid misunderstanding again.
Thank you.
Regards,
Eva Kemp.
