Product combination: definition
A combination, also called a variation, is a specific version of a product resulting from a cross of its attributes, for example "T-shirt, red, size M".
Each combination has its own stock life
In PrestaShop, combinations are managed in a product's Combinations tab, once attributes have been defined under Catalog > Attributes. Each combination has its own stock, independent of the others: a red T-shirt in size M can sell out while size L stays available, without affecting the product's overall display as long as one combination remains in stock.
A combination can also carry its own price adjustment relative to the base product, which makes it possible, for example, to charge extra for an XXL size. For an online seller, precise combination management avoids two common problems: selling an item that's actually out of stock in a given size, or needlessly hiding an entire product when it's still available in other variants.
