Making dropdowns for an automotive site will make you a sad panda if you have to do all the work yourself.
Don't be sad, just
script/plugin install git://github.com/itspriddle/cars.git
You probably want to use this in a Rails Helper.
module AutomotiveHelper include Cars end
<!-- Show dropdown for all makes --> <%= select_tag('makes', options_for_select(makes)) %> <!-- Show dropdown for Acura's models <%= select_tag('models', options_for_select(models['Acura'])) %>
