i am new to struts2. I want to create a registration form, in which first i have to select type of members. (To select type of member i gave there s:radio) After selecting member type my member will move on select tag, here he will select category he belong(category is selected from s:select).
But i want to display on those category in select options which are belong to type which is selected from s:radio. So my problem is i don't know how i change options of s:select based on s:radio option selected by member.
