I have two list/menu in my form. Is there any way to make second list/menu option changes dynamically based on chosen option in first list/menu? Example: first menu has three option eg: A, B, C. If i select A then after selecting it 2nd list option will be : X, Y. But if i select B in 1st menu then 2nd menu option will be : V, W and so on. And it's all happens before submitting the form

How to do that? Thanks
