Hello Philip,
Thank you for your answer. I was talking about droplist. as you can see on my screenshot I have a button with a label who says "Choose options" and redirecting to the produc page. I'm searching a way to have droplist directly on this page with variants and the add to cart button.Actually, iIt is not the case and I don't find a way to set it.
Here is my menu setting
and here is the category listing
as you can see, for "millesime" I have a list of values instead of a droplist.
To be as complete as possible, here is the product page
