Contrain number of pick list selections / override "allow mulitple values"?

[nxpet]

Hi, I have a pick list that has the option "allow multiple values" checked. I would like to use this field for another item type, but with "allow multiple values" deactivated (single selection only). Is there any possiblity to do this with the same field or do I need two different fields?

The "overrides for fields" can not change this property. With the types contraints I do not see how to do it. Is a trigger the only option? But using a trigger, the GUI still would show that field as multiple value?

Any ideas?

Thx, Timo

It's not currently possible to do within the product. Either a field is multi-value or it's not.

It's possible for a trigger to check if there are multiple values in the pick list, but the GUI would see multiple values.
