I’ve build a small custom widget to fill a choice list of numbers, with the help of a grid.
The grid actually resembles a vial box:
Looks great! Is this just an experiment, or are you using it for something?
By the way, you can append /m/fork at the end of the doc URL, this will open this document in a fiddle mode and let others play with it more quickly.
Yes we use it to easily (and graphically) fill the position choice list. Since one “position” actually is a position in this box.
The user of this document put and get vials from these vial boxes (which is stored in our -150°C freezers).
