Anitha,

As per the requirement you hav posted,

When an first option box is clicked

a new set of Collection is need to be loaded,

so when the First OptionBox is Clicked (Using OnClickOption)- It need to be forwarded to a new

Action - Where it can load the another set of Collection for the Next

OptionBox. Similarly for other optionboxes.

NOTE:
The Values of the optionbox need to be Persisted every time a new Click is made.
