You cannot specify a "Drop-down" field as the record title.
However, you can use a "Text" field, which can be specified as the record title, to display the content of a "Drop-down" field as the record title.

Configure automatic calculation for a "Text" field in such a way that the content of a "Drop-down" field is entered in the "Text" field. Then, specify the "Text" field as the title field.

  1. Check the field code of the "Drop-down" field you want to specify as the record title.
