during signup by applicant he/she must fill her educational details , total 5 educational levels,

1.ssc

2.hssc

  1. BS

  2. MS

  3. Phd

now lets say that an applicant has only BS passed then it mean that he/she would not have fill 4 and 5 option, now i want that there should be an option in signup page to add rows dynamically , say for 3 levels of education only to add and fill 3 rows of text boxes, so how ?

or if u ppl have any other alternative then share please

Here is my Database table structure to which i want to add data from asp.net(c#) website.
