I cannot change dynamically the quantity +/- of each product added in the basket

:joy: :joy: Sorry Master.

Here, on this page of the “Detail Product”, I preferred to put static components .. while I had the problem here on the forum how to activate the static button to add the product to the Cart (Panier) via the shema if you remember

The problem had exceeded me. I only fled this part of the application. Otherwise, concerning the +/- static buttons I succeeded.
