Mediclean Pro theme only has four “Menu Locations” available in the theme to assign for different theme sections.
Currently, the hamburger menu displayed in the mobile/responsive views is the primary menu displayed in the desktop sites and hence it is not possible to show different menus for mobile views and desktop views as they are controlled from a single menu location in the theme.
If you wish to get a different menu for mobile only you might need to add the feature through external third party plugin like megamenu or any other services.
However, please note that as any third party menus have not been tested with the theme, we cannot assure you for the 100% compatibility of the third party menus with the theme.
If you have any confusion/queries further, please feel free to write back to us.
