For ex,
The sub category list box depends on the category list.
If the category list is selected, send the Id through ajax and get the sub categories based on the category Id by the query then show the values.
Use jquery,CI

Take a look at jquery.com
Code:
$("select[name=select_numero_1]").change(function(){get_select_2($(this).val()});
function get_select_2($select_1_value)
{
$.ajax({
type: "POST",
url: "<?php echo base_url()?>ajax/get_select2",
data: { select_value:$select_1_value},
async: false,
dataType: "json",
success: function(msg){
//msg is a json object you can use to populate you select with
}
});

In CI it is the same as without CI.
You include jquery. In your ajax call, you call a controller that parses som information back.
