Addons This section is used to add Addons  to Variants; it is possible for each Variant on a product to be assigned a different combination of Addons. If not manually set, the default is to apply none.  This section allows products to be edited individually; editing in bulk is done with other tools, such as the CSV Upload  or the  Bulk Updater . You may use the tick boxes to select all of the Addons which are available for each Variant.
