Topic: Simple product attributes

Hi,

I don’t find how to have several attributes (not variations) on one simple product. I have 15 shirts on my shop. Every single shirt has one colour, one size, one material. No shirt have variations. For instance:
– All the shirts #1 are: Blue / Large / Cotton
– All the shirts #2 are: Red / Small / Wool
– All the shirts #3 are: Purple / Medium / Cotton
– All the shirts #4 are: Yellow / Small / Cotton
And so on…
When my user is on my shop page, I want he can apply filters to find the colour, size or material he wants.

How can I do this?

I have tried to get information but I have only found information about how to set up variations on one variable product…

Many thanks.
