how to match attribute for accessories (related product)

[mmleoni]

Hi guys,

 my problem is: how can I match the attributes of an accessory?

let explain: main product are shoes, accessory is a belt. If I select/take the red shoes, the system have to show/add to cart the red belt, or, at least, it has to ask the color of the belt if someone tries to add the belt to cart.

 

(really I'm working with posters and frames...)

 

any idea?

 

bye,
