For example: Under "Treatments" category, I have: Option 1, Option 2, Option 3, etc... Then under "Hair" category, I have Option 1, Option 2, Option 3, etc.. I need each option to be displayed in each category as per the layout URL above.
I tried but all the categories are showing on all the menus.
In the meantime, you can submit ticket on category: OS Services Booking and provide your site url with super admin account. I will help you to add custom code to allow administrator to select category for showing services
