And the span content can be modified when you're using variants in a non-listing mode. 2 - These are used by the add to cart for the global product page. Even if you have variants in the listing mode ; you might have some products without variants. Regards, --- Jerome - Obsidev.com HikaMarket & HikaSerial developer / HikaShop core dev team.
