Dependent answers

[paolodm]

I would like to be able to hide certain answers based on the user's previous answers in the survey. For example:

q_1 "What kind of pets do you have?"
a_1 "Cat"
a_2 "Dog"
a_3 "Fish"

q_2 "How many of each pet do you have?"
a_1 "Cat", :string, :condition => (q_1, "==", a_1)
a_2 "Dog", :string, :condition => (q_1, "==", a_2)
a_3 "Fish", :string, :condition => (q_1, "==", a_3)

So the a_1 Cat option in q_2 will only appear if I selected a_1 Cat in q_1.
