Picklist + custom settings

HI All,

I have a page which contains many fields out which 2 are region and country,these 2 are picklists.
i wanted to populate values into these 2 fields from custom settings. problem is i wanted to country values based region values.
Ex: say i have region like APJ,EMEA.
for APJ i have countries like india,indonesia,australia,
for EMEA i have countries like US,UK,.
when i select REgion as APJ i have to show only india,indonesia,australia in the country field.
for this do i need to create 2 custom settings ?and how to achieve the above functionality in VF Page.

Thanks
Lakshminarayana

You can dynamically add the value to the picklist in the controller class 
List<SelectOption> options = new List<SelectOption>();
  options.add(new SelectOption('APJ', 'APJ');

Set the onchange event in the region picklist and rerender the country picklist.
Set the if condition while adding the options for country picklist like below 
if(Region = 'APJ')
  options.add(new SelectOption(India, EMEA));
  //Add other apj regions
else if (Region = 'EMEA')
  //Add EMEA regions
