Help identifying javascript library

Can anyone help me identify which javascript library allows you to choose an item from a DropDownList and the selected item is then added to a 'tray' which can be removed if necessary??

Could you please direct me to some examples?

Could you send us the website link you have taken the screenshot?
It could be JQuery or a commercial library.

Uhmm, hard to say, you a better off using IE developer tools (Press F12) and have a look at the elements  themselves, you can enable the profiler when using the "tray" so that you can identify the JS calls, then those calls are linked to the loaded JS file that hopefully will contain the library name and version at the top.
