Placing hidden textbox on web page

Tapan Desai

I want to create a registration form for my project where, when a user has to fill in the fields for registration. One of the field is of "SECURITY QUESTION" where the user is provided with some questions from DropDown Box but if the user clicks on "SPECIFY YOURSELF" option a "TEXTBOX" should appear right below the the drop down box for the user to enter this manual question. The sample of such thing you can see when registering for a yahoo id. So can anyone tell me how can I do that? Any help would me very much appreciated.. Thank You in ADVANCE>

Manual security question and answer will user specific.

Better dont store it as Master data, create another table with user mapping or update exsisting User Master table column.

Thank You Mr. Suthish Nair. Can you help me at one more thing? When the user selects any question from from DropDown List that question should be stored in the Security Question column of my database and if he enters the question manually that should be recoded in the database in the Security Question's column. How can I do that? Will I need to create two separate columns or it can be recorded in the same column. It will be very helpful if can create sample file and attach it here so that I can download it and have a proper understanding by studying the example. Thank you once again...

hi,

keep the style="display:none;" on client side for the text box and when user select "specify yourself" then call a javascript which set the textboxclientid.style.display='' or 'block'.

This will definetly help you.
