It is not possible to specify a Drop-down field as a title field.
Fields that can be specified as the title field

However, you can display the content of a Drop-down field as a title field by using a Text field.
To do so, you need to set a formula to display the content of the Drop-down field in a Text field, and then specify the Text field as your title field.

Steps

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