Gift wrapping in ATG Store is applied to the entire order. It is not possible to select gift wrap for individual items in an order.
The /cart/gadgets/giftWrap.jsp gadget on the shopping cart page invokes the /atg/store/droplet/ShowGiftWrap servlet bean to determine if gift wrapping should be available for the order. This component is a CRS-specific servlet bean of class atg.projects.store.droplet.ShowGiftWrap.
If the giftWrapEligible property is true for every hardgood SKU in the order (i.e., everything except for gift certificates) the ShowGiftWrap servlet bean renders the /cart/gadgets/giftWrapRenderer.jsp gadget, which displays the gift wrap options:
StoreCartModifierFormHandler manages adding the gift wrap and gift note to the order. Gift Wrap is an actual SKU that is added to the order if gift wrapping is selected.
