I have made a sign up form which asks user to enter his personal + Academic details and EMPLOYMENT INFO, i am done with personal and academic details section and also designed EMPLOYER INFO section but as u know that it isn't necessary that every person would have employment experience so i provided an option with YES | NO..... so i want that if user click on YES then EMPLOYMENT INFO section appears and if no, then disappears. i have kept employment info within <DIV></DIV>,
e.g http://www.bayrozgar.com/signup.php
have a look at employment section
