class_docstr: Creates a dropdown of choices from which entries can be selected.
  Preprocessing: passes the value of the selected dropdown entry as a {str} or its index as an {int} into the function, depending on `type`.
  Postprocessing: expects a {str} corresponding to the value of the dropdown entry to be selected.
  Examples-format: a {str} representing the drop down value to select.
