Drag and Drop functionality in webdynpro java

Hi all,

I am trying to implement drag and drop functionality in item list box. I searched in sdn and got this blog[Drag & Drop|https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/11981] [original link is broken] [original link is broken] [original link is broken];

In this blog it is being referred to use 'dragsourceinfo' and 'droptargetinfo'. I am not able to understand what are they refering to by these names. Which is the UI element to be used for this?

Pls help.

Thanks & Regards

Ramanan
