i can create a field with radio button with yes/no but i need like this
what type of os are you using?
if user clicks A then the radio buttons like
A1- windows 98
A2- windows vista
A3- windows 7
should be available for clicking without refreshing page
is there any module for that...i am new to drupal... this might sound silly
Module is preferred getting into coding is hard part for me...
Thanks in advbance
