Hello matteoasten,
1. No, I am afraid negative value can’t be used for addon prices. It’s meant to only add on top of the main price, not to substract. I’ll discuss with the team if it’s possible to include this is some of the next update (can’t promise, as I am still not sure if it’s possible at all)
2. I am afraid I don’t understand. Could you, please explain more? What do you mean by “to collapse Lafka Global Add-ons on page menù”
3. These buttons can be configured for variable products only. You’d need to enable the checkbox for every variation. However, with this feature users would not be able to choose addons.
The easiest way to see how it’s done is to import the demo and check some of the Pizza products.
Regards,
Dimitar
