i wanna do something like this :
if a customer press on the color it shows the sizes available, if the customer presses on size, it shows the color available.
In my confiburable products all i can do is to select the color and then the size.
If i change it and put the size first, i choose the size and then the color... i want them interchangeable...
I don't know what i'm doing wrong
It seems you could use the Configurable Swatches: http://docs.magento.com/m1/ce/user_guide/catalog/product-configurable-swatch.html
