When a customer wants to buy a T-Shirt he has to choose the color first and then he can choose the size. But I want him to do this also the other way around. So that he can choose the color or size first. At now, he is not able to choose the size before he chose the color.
Hi Galdoran and welcome to MageOverflow.
What you want is no problem, you just have to implement the logic for this which lays in
js/varien/configurable.js again, but the other way around.
Magento generates a data structure with all possible ways if you choose one attribute after another.
If you want ALL combinations, this is a lot, so not practical.
I recommend to not do this.
