I have the website www.naturalfarmerspantry.com.au and we are running the Debut theme. The menu structure on desktop is not working well as the sub categories copy appear over other primary categories copy. I want to implement a burger menu structure for desktop. Mobile menu structure is fine. Step by step solution will be greatly appreciated.
Generally, to recreate a Hamburger menu for the desktop will require a substantial header section modification from a web dev.
A similar question was recently discussed in this thread.
It will need a lot of changes in CSS. It will be difficult to have a detailed instruction because it takes a lot of time.
You need to hire an expert or someone who can login and change the code directly for you.
Hope it helps!
