The ScrollablePromotionalContent-ATGSlot and ScrollableProductSpotlight-ATGSlot cartridges display a scrollable hero image and a scrollable set of featured products on the Default Home Page. The ScrollablePromotionalContent-ATGTargeter and ScrollableProductSpotlight-ATGTargeter cartridges are not used out of the box but are available for developers who base their application on Commerce Reference Store. The content for these cartridges is provided by ATG slots and targeters that have been defined in the ATG Control Center and the Business Control Center, respectively. All four cartridges, collectively referred to as the “scrollable targeting cartridges” in this section, have a similar structure, described below.
