Hey Mark,
You shouldn't need to modify the callback. All you need is to alter the theme_location
which you almost got right. You need to make sure that you have return $args;
in your beans_primary_menu_args
callback function (after the if statement).
If you are using the offcanvas menu on mobile, make sure that you apply the change onto the beans_primary_offcanvas_menu_args
filter too 😉
Happy coding,

Can primary menu be set to offcanvas menu by default? side menu instead of header .
