Multiple html pages ?? can it be done

Question

Hi

Well my present query is bit tricky i feel

I have created a webform.aspx which contains many dropdowns textboxes and checkboxes... there are two buttons...one is ADD REQUEST...and the other is SUBMIT REQUEST... 
Q. ADD REQUEST button Functionality: A new HTML form should be generated in the bottom of form before submit button.e-g: when i click on the request1 checkbox then the values of all textboxes and dropdowns of request1 checkbox should be filled in the bottom HTML form but should not be submitted to database until i press submit button.similarly when adding new request by clicking next reqest2 checkbox the same procedure should be followed and another HTML should be generated of the details of request2 checkbox in the bottom of previous HTML form.
HOW TO REPEAT THAT HTML FORM ON EACH CHECKBOX SELECTION.

I dunno whether question is clear or not .. its my friends query ?? 

Thank you
