I have the same problem described in this post (Adding separate order tags, not updating/changing current order tag), however the adopted workaround is not the best I guess.
Maybe there’s a better solution now ? (after some years)
How can I have multiple tags in a ticket? OR How can I have “free edit” tag under each order line?
Can you share your Order Tag group settings? If you set Min to 0, it should not overwrite it.
Is set to min 1. I guess if I set to “0” will allow to have it empty and waiter may forget to imput it.
Correct
Minimum 1 means it will require waiter to input at least one option from this list.
Now, if you are expecting waiter to need to input more than one of 20cl option for Birra, then you have to set in General Settings > Max to 0 and on this Order Tag List line, in the column Max Quantity line set 100.
