title: Adding dynamic drop down components in JSF
body: <p>My requirement is like this. I have a selectMenu with some values (Examples: Engineering, Medicine, Law etc..,) . Suppose if I select Engineering in the drop down, I want another dropdown menu created dynamically which has values related to Engineering (Example: Electronics, Computers, Electricals etc..,). How do I achieve this in JSF 2.0 ? </p>
