When selecting a dropdown item how do I get a specific list of questions to appear .net / html

Please don't give me the outright answer, I'm a newb and I'm stuck - just need pointed in the right direction.

I have a dropdown with 4 values (in html) and I would like a list of questions to pop up for each of the values in the drop down.e.g dropdown item 1 = question list 1; dropdown item 2 = question list 2.

My search keeps pointing me to a table pulled from sql, but I don't want that, I only want a form that is submitted to sql after the specific list of questions is answered.

I'm building this in visual studio so will need .net help

Thank you so much smart people!
