Lets consider UK country id is 1.
$CountryId=1;  //Change as needed
SELECT Cnt.country_name, City.city_name
FROM country Cnt join (city as City)
ON (Cnt.country_id=City.country_id)
WHERE Cnt.country_id=$CountryId

Expanding on the above, what you need is a multi dimensional array:

The easiest way to do this is to generate a $objCountry=db->query() of the countries you want and then loop through each country record and build an array/object by running the query above setting $CountryId to the value in the $objCountry->row()

you want to build an array/object that looks like this:

$citylist = array(array(ID=>1,Code=>'UK',cities=>array('Birmingham','Bristol','Cardiff'...))

you can then pass $citylist through your $data to your view
($data['citylist'] = $citylist

where you can then run for each loops on the nested data and format it however you want.

Best of luck
