On the POS your products with variants will behave very much like you would have seen when using sub-categories for variants. In our example we've created a product called 'T-Shirt' with variants in size and colour and assigned it to a category called 'Merchandise' which is intended just for products with variants (a product with variants can be assigned to any category).
In our example a customer has asked for an extra large, grey 'Game of Thrones' T-Shirt. First open the category where this product is located.
