SuperSportowy online store has been created using Prestashop engine. Aside from standard implementation of the store along with its original design we have completed a range of additional modifications at the Customer's request. These included: the blog module, menu following when scrolling, animated banners appearing depending on the category, a scrolling graphic list of logotypes also generated based on the selected category, adding information about available variants on product lists, integration with payments, integration with the chat enabling contact with customers, an individual template and integration with Allegro website that easily supports a customer managing e-auctions and stocks of their products.
