I have a product that comes in many colors, but not all colors come in all sizes. My page has 2 select boxes, one allowing the user to select a color, the other allowing the user to select a size.
Is there a way to filter the options depending upon the user's selection? So, if he selects a color, the sizes shown are those available just for that color, and if he selects a size, the colors shown are those available just for that size?
