Popup with a magnifying glass [closed]

I have a page with a combo that allows multiple selections of your items.

If the user selects only one item, closing the combo displays text about the selected item. if the user selects multiple items, when closing the combo the displayed text is "X chosen", where X is the number of selected items.

I know that if the user reopens the combo he can see the selected items but I want to create a button with a magnifying glass to be placed next to this combo which, when clicked, displays a popup with the list of items selected in the combo.

Hereisthecombocode:

<scripttype="text/javascript">
    $(document).ready(function () {
        /*PRODUTOS*/
        $('#produto').multiselect({
            includeSelectAllOption: false,
            nonSelectedText: '[Selecione uma opção]'
        });
    });
</script>
