I would like to have a Drop Down question whare choices depend on teh answer to a previous question.
Question 1 (radio button): What kind of pet do you have? Dog / Cat / Elephant
Question 2: (Dropdown) What is your favorite brand of pet food: When user clicks on the Dropdown he is proposed a list of animal food brands depending on answer to question 1. List must be the result of a query in a database.
