Selling variable products? It’s likely WooCommerce doesn’t handle your variations how you want it to. It hides away variations, such as colours and sizes, on single product pages – with barely any control over their display. That’s where WooCommerce Show Single Variations comes in: this plugin gives you complete control over how, and where, variations display in your store. You can easily show product variations on your shop page, with clear images and their own add to cart buttons. Your customers can see exactly what your products look like and what options are available, without having to dig around for details.
