Hello, @mabulborneo Since this feature is not available on our theme and needs lots of code customization, we cannot help you out on this issue from this forum. If you really want this feature, you can contact our customization team. https://themegrill.com/customization/
As per adding a feature in theme, I’ll discuss with our team. But it might not approve. You can also try searching for a plugin with that provides such functionality. Regards, ThemeGrill Support Team.
