I have a picklist that I can only edit in full edit. The UI type is 15, I checked the displaytype (1), readonly(2) and presence(1). Am I missing a setting?
If this picklist is in a picklist dependency, you can't edit from Detailview, because we need access to the other picklist to check or modify the values.
Can you check if you have a picklist dependency with this field, please?
