When you sell products with an EU energy label online, the energy class must appear near the price as a coloured arrow that opens the full label, with a link to the product information sheet. Enter each product's class, label image and information sheet once. A block on the product page draws the arrow in the official colour order (A to G, A to E for tyres, older A+++ scales) and opens the label on click. Texts appear in 10 EU languages.
