| I have two drop down. In first drop down it shows the state name and
in second drop down it shows city of that state. but i want if any
particular state is selected then its corresponding state should be
selected in another drop down. I think onchange event is require to
write on first drop down but i dont want to put any submit button. I
want if first drop down is selected then its corresponding data should
be displayed in another drop down.
