Displaying Dropdown list value on selection of other dropdown list

Hi all,

I want to do like following,

I have Zone dropdown list, which contain West Zone, South Zone etc.
when i select a value from this, i want to display all the regions in
the selected zone in Region dropdown.

What I have done is something like this, but it is not working good
for me

  <% @r= Zone.find_by_sql("select id,ZONE_ZoneName from zones")%>

<% for item in @r %>

"><%= item.ZONE_ZoneName -%> <% end %>

This calling the controller but the selected parameters are not pass
to the controller

I am doing this way.

Is there any other way to do this?
please help me, I am new to ROR

Thanks and Regards,
Shripad
