Can I convert a multi picklist to a single picklist?
The picklist is currently hidden and has not been used, so no values will be lost. Will Salesforce allow me to convert the multip picklist field into a single picklist field or will I be forced to create a new field?
If you go to the field in setup and click edit, you should see an option to "Change Field Type". If you click that button you should be able to select Picklist from the list of options. You should get a warning message that says all of your data will be lost, but since you don't have any you should be fine.
