The import wizard only allows values to be imported into a dependent picklist if they match the appropriate controlling field. This ensures data integrity and prevents invalid values from being imported. Custom picklist fields can be either controlling or dependent fields. This allows the app builder to create custom dependencies between custom picklists. Checkbox fields can be controlling fields but not dependent fields. This allows the app builder to create dependencies based on checkbox values, such as true or false. Multi-select picklist fields can be dependent picklist fields but not controlling fields. This allows the app builder to create dependencies based on multiple values selected in a multi-select picklist field. Standard and custom picklist fields can be dependent fields, but not all standard picklist fields can be controlling fields. Some standard picklist fields, such as Lead Status or Opportunity Stage, cannot be controlling fields because they are used in other processes, such as lead conversion or sales path
