I thought to use a characteristic for colors and a custom field for sizes, but every product has his own colors and his own sizes: there are trousers that have from 34 to 60, others from 38 to 56, from XS to XXL... no one coincides, and with colors the same thing. And almost all my catalogue is like that.
I waited for a better news (I was praying for it) but I think just a hard and long, long work wait for me
With regard to other questions, I suppose i won't have any problem.
Thank you anyhow for your time, but if you have a great idea about this, I'll waiting for it
