Question:
How to change the design of the opened Hamburger Menu.
Product:
The problem is related to Wix Studio.
What are you trying to achieve:
I want to design a simple drop-down or sidebar hamburger menu, as the industry standard is. I do not want this forced background big centered font menu, that Wix is somehow forcing me to use 
What have you already tried:
I tried to restyle it but there are many restrictions from Wix. I read all the helping center material and tried to find another answer in the internet - with no success.
