multiple variables for product node display
I'm having a mental block trying to display a product display node. Using the demo site as an example. There is the top level category display of "wearables'. Then there is a t-shirt 'All Tied Up'. There is the drop down menu to select size. How can another drop menu be added to display here. Say, for instance, there is a v-neck, standard collar, or deep-v-neck option. And three color option (white, black, or gray). I get how to make these as all different products with different SKUs. But the node display with another drop menu (other than the size) is where I'm hung up.
