Hello,While adding new items to the K2 i need to choose the list of Authors in the 'Authors' dropdown, So how can i do that in k2.ThanksDinesh

The list works exactly the same as it worked in joomla articles. On the right of the item page there is the Author & Publishing Status. There you should be able to select in which author you want to assign the specific item.

@Yiota : Yes it works like that but the list is limited to backend users. If you want to see a full author list, you have to modify the default backend K2 item view.
