Clicking on list box opens control to allow adding to list

I am developing an asp.net application where there are several listboxes I need users to make selections in.   I would like it so that when the user clicks on the box (or perhaps a button beside the box) a pop up allows the user to add and remove items as follows.

Here is the list box in its normal state:

List box Normal
When the user licks into the box the following pops up allowing for changes:

Listbox selection control
Clicking off this control will return the user to the page and the target listbox control will reflect the changes.

I have seen this in action but can't find one to give as an example.

Hi, maybe you can use Drag and Drop feature

There is a jQuery for this
http://jqueryui.com/sortable/#connect-lists

It is also possible with HTML5

Both are easy to implement

Thanks but not quite what I'm after.  

The page it is on is very busy so I'm trying to conserve space.  I need the listbox  to kind of expand out to include a selection box when it is clicked.  This way the space is used when it is needed but once the selection is made only the selected items are shown.

Test page : http://jsfiddle.net/L9VhF/

    <select id="listbox" multiple="multiple">
        <option>red</option>
        <option>green</option>
        <option>blue</option>
        <option>pink</option>
    </select>

<div id="dialog">
    <select id="a" multiple="multiple">
    </select>
    <table>
        <tr><td><button id="pop">>></button></td></tr>
        <tr><td><button id="push"><<</button></td></tr>
    </table>
    <select id="b" multiple="multiple">
        <option>red</option>
        <option>green</option>
        <option>blue</option>
        <option>pink</option>
    </select>
</div>

Open in new window


jQuery(function($) {
    $("#listbox").click(function(evt) {
        evt.preventDefault();
        $("option", this).each(function() {
            var text = $(this).text();
            $("#a").append($(this).clone());
            $("option", "#b").filter(function() { return $(this).text() == text; }).remove();
        });
        $("#dialog").dialog("open");
    });
    $("#dialog").dialog({
        autoOpen: false,
        modal: true,
        width:250,
        height:200,
        resizable: false,
        draggable: false,
        close: function(event, ui) {
            $("#listbox").empty();
            $("option", "#a").each(function() {
                $(this).clone().appendTo("#listbox");
            });
            $("option", "#a").appendTo("#b");
        }
    });
    $("#pop").click(function() {
        $("option:selected", "#a").appendTo("#b");
    });
    $("#push").click(function() {
        $("option:selected", "#b").appendTo("#a");
    });
});
