I really can not understand the western programmer's thoughts and the way they think when developing an software like prestashop making setting attribution combination a real headache that i will switch to other software when I found one. The truth is in china the combination issue is really a piece of cake when you operate in taobao.com backend, or aliexpress backend, you just assign a photo to each product color, the color thumb will show the photo you assigned to it, and you choose by clicking on the photo, and about the material, size, style, any other attribute, you do not have to think about that, the software just do it for you.
With the time assigning photos for one item in prestashop, I already finish with 30 more products at aliexpress backoffice, and the productivity differ further much when you have more attrubute group with much more value.
One of my Chinese friend really can not understand what a stupid attribute combination generations it is with prestashop which has been developed for so many years still this urgent and must-be-eased function is far far away from your can imagine.
I am done with this.
