Dynamic choice list

[ReneAubut]

We have a choice list for a set of around 300 wells. Once a well's data is collected, is it possible to have it's id not appear in the choice list, or if it is selected again, display a warning indicating it was already inspected. This way the choice list would gradually become smaller until all wells were inspected. Thanks

There is my old school way or you can use javascript.

Hope it helps.
