Lets understand how to create a two dimensional javascript arrays. First create a singular list of arrays

var country0StateList = new Array("Country0-State0","Country0-State1","Country0-State2","Country0-State3");
var country1StateList = new Array("Country1-State0","Country1-State1","Country1-State2","Country1-State3");
var country2StateList = new Array("Country2-State0","Country2-State1","Country2-State2","Country2-State3");
var country3StateList = new Array("Country3-State0","Country3-State1","Country3-State2","Country3-State3");


Create an array of arrays with

var countries = new Array(country0StateList,country1StateList,country2StateList,country3StateList);

Voila, the variable countries now is a two dimensional array.
