Second example of using carousel mode in a theme.
In this theme I’m doing a vertical carousel in Content Explorer with system images for box art.
In order to see the system images you will need to configure:
Configuration -> Customisation - > Hide Grid Mode Box Art to Disabled
NOTE: You will need to be on version 2508.3 Golden Goose to use this theme.
