Table design using Ruby on Rails

I have a model named OrderingRequest I am using state_event_machine gem
to record different states,I have states called order_place and
order_reject. When I click order_place a dropdown with 3 values should
display and also some other values in drop down should display when i
select order_reject, my question is how to design this order_place and
order_reject data and associate with the my current table
