Publish products with just the attributes it has
Hello, this is a completely newbie question.
How do I have to add a product and how do I display it ?
For example, I need to add a shirt with blue, black, green and small, medium, large.
If I publish that, it appears with all the sizes in the system and all the colors in the system, instead of just the availables for that product.
How can I do that ?
Thanks in advance.
