make a dropdown custom field with 'cities' list in it

Question

I am developing a website for real estates. I was wondering that how can I add a dropdown to my custom forms (theme my login plugin) for cities states etc. The basic point is that I dont want to add new tables in the database. I want to achieve this without that.

Thanks

You can register custom taxonomy like so:

<?php
// Register custom taxonomy for locations
function mamaduka_register_taxonomy_location() {
    register_taxonomy( 'location', array( 'post' ), array(
        'hierarchical' => true,
        'label' => 'Locations',
        'public' => true,
    ));
}
add_action( 'init', 'mamaduka_register_taxonomy_location' );
?>
