country and state select

Hi
    In my application I have to implement a country select box as well
as state select box. Is there any rails helpers available for this or I
have to create these from my own tables ? Please share your thoughts
which is better

Thanks

Second link in each case. There are some other options as well depending on what exactly you want to present.

My advice would be to find a plugin. Why reinvent the wheel?
