Creating smart form

Hi

I was wondering – Is it possible to create smart form:

Choosing Option A from Drop menu – Than new Checkbox options opened and the user need to select.
If the user Choose Option B from Drop menu – Than Text box opened and the user need to write something.

Is this possible to create?
If not, Do you know plugin that does that?

Thanks
