When you deactivate a value, it no longer appears in the picklist that users select from when creating or editing a record. But records that already had that value retain it.
Let’s say you want to hide a picklist value so that users can no longer select it. First, navigate to the picklist definition.
- For a picklist on an object, go to the fields area of the object. For example, for an Account picklist: From Setup, enter Account in the Quick Find box, then select Fields under Accounts.
- For a global picklist: From Setup, enter picklist in the Quick Find box, then select Picklists.
Then go to the picklist’s detail page. Remove the value from future use by clicking Deactivate next to its name.
The value moves to the Inactive Picklist Values section. If you decide later that you need the value, click Activate next to the value name.
