Hi,
I probably explained myself badly.
Try going to this page please:
https://packservicesit.eu.mywoocart.com/categoria-prodotto/contenitori-in-plastica/taniche-e-canestri/
and please watch my video, so maybe it’s clearer. I don’t understand why the unavailable options are not automatically deselected on the product page.
