Hello,

1. All necessary options are enabled in Theme Settings, only left to define titles for each footer column and the accordions should be enabled: https://take.ms/fsc7D , https://take.ms/dDjLW

2. Only tabs can be changed to accordion on the product page, I see that you use Layouts, so define this element: https://take.ms/uLuo7 and enable the accordion here: https://take.ms/dE4dz

Kind Regards
