There are three properties related to the appearance: Preselected: gives
a question a default value so that the question has a preselected answer,
when the respondent completes the survey. The designer of the survey sets
the preselected value.
Hide question: takes out - disables - a question from the questionnaire,
without deleting all information, so that the question can be reactivated.
Note: This property is not listed in the Properties panel. You can hide a question by not checking it in the list of questions. To show a hidden question, just check it again.
Show heading: prints the heading of the questions on the final layout. By default it is deactivated.
