Multiple selections in a ComboBox

Question

Hi there!
Is it possible to make multiple selections in a ComboBox ?
i.e. make n consecutive selections and store them in an array
or make n selections in the open list of the CB by using (for
example) the click-Shift Key keystroke
Purpose is to allow the user to select multiple different
issues of a magazine with a maximum ease of use...
(Code I use is attached below)
Many thanks for your help!
Best regards,
Gerry

(with the labels) and calculate its amount (with the data)?"
Gotcha - and sure you can.
OK, let's see - you have this (sort of):
var CBBUYListener:Object = new Object();
CBBUYListener.change = function(evt:Object) {
I'd change that to something like this:
var comboSelected = new Array();
CBBUYListener= new Object();
CBBUYListener.change = function(evt:Object){
//first check to see if this item is already selected
var didSelect = false;
for(var i = 0; i < comboSelected.length; i++){
if(comboSelected
== evt.target.selectedIndex){
trace("already selected this item");
didSelect = true;
break;
//if not selected add this index
if(!didSelect){
comboSelected.push(evt.target.selectedIndex);
CBBUY.addEventListener("change", CBBUYListener);
What you get now is an array - comboSelected that will
contain the selected
indexes from the combo box - CBBUY.
You want a sum of the data:
function sumSelected(){
var sum = 0;
for(var i = 0; i < comboSelected.length; i++){
sum += CBBUY.getItemAt(comboSelected).data;
return sum;
You just get each item's data from the comboBox, at the index
specified in
the comboSelected array.
