Hello! Thank you so much for your answer. I just saw it!
Here is the link to one of my product page.

Actually, because I have used an external, print on demand extension (Art of where) to generate my product page, the regular « delete » tool doesn’t work. I already contacted the Squarespace help and they confirmed this.
I think I need to enter some css code to force hide the drop-down menus.
Attached, some screen captures to explain what I need and what happens when I try to delete a variant —-no delete.
thanks again!
