Hi & happy new year. We are xikado.com, the only startup who get customized chocolate orders (imprint &engraved chocolates as well as chocolate bar) from customer completely via our website and make his/her chocolate.We service in middle East. We use fancy product designer ,allow customer to design his chocolates himself. Now, we are going to release our chocolate bar(a tablet chocolate covered by nuts, dried fruits, herbals and ...). We want to make a limit that customet can just add 4 or 5 ingredients to chocolates (e.g Walnut, pistachio, hazelnut, almonds from 15 different ingredients, not more) and each additional ingredient would have a price. Every ingredient shown by a picture can be chosen by customer and illustrated on chocolate. But no limit on adding would become an issue to us. Please advise an instruction to solve the issue. Regards Hassan
