Asp.net dynamic structure

I want to create a website where it is possible to add dynamically "X" dropdown-lists (or other elements)

These dropdown-lists should be shown on the website and furthermore there should be an other 开发者_如何学运维element be shown, that depends on the dropdown-list (for example: if the user chooses option "A" there is a checkbox, if the user chooses "B" there is a input field)

Is this possible with ASP.NET (Vb.net)? (I know that this works with PHP)

thanks in advance

Yes, it's possible with Asp.Net. But my advice to you is to do it with javascript framework such jquery or ExtJs without request to server.
