Dependent picklist and global picklist are two options that can be used to meet this requirement. Dependent picklist allows users to create a conditional relationship between two picklist fields, where the available values in one field depend on the value selected in another field. Global picklist allows users to create a set of picklist values that can be shared across multiple fields and objects, ensuring consistent values and reducing maintenance.
