In the shop I'm preparing, products are sold in various colors. Use the "Filter" (Layered navigation filter) I would like you may find, among other things, also for color. In "Catalog" has been created a "Product Feature" call "color" with the whole list of colors. Each product is associated with its color. The problem is I when the same product has more colors at once since in the "Features" I can only choose one. For example: I have a light brown and white. I can put the product as "White" feature. But if the "Filter" (Block navigation thick) the user selects "brown" clearly will not see that lamp. There is a solution or a module that can do this? Thanks in advance for advice and guidance. Carlo P.S. Since there are many variables, it is not functional feature set the example: White / Brown. And if there was only one white and the filter product is selected "white", you would not be displayed with the product feature White / Brown.
