Question: In Mac, in skype when we add users to an existing chat, by clicking '+' button on top, a beak like window appears carrying a token field like control. When an user types some name in it and a match is found then a list appears carrying user icon , status icon and his/her name. Also the width of dynamic list is same as beak window.

Can any one suggest some way to create similar control?

Thanks in advance,

Answer: 
[`NSTokenField`](http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSTokenField_Class/Reference/Reference.html).
The control for the list would be [NSTableView](http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSTableView_Class/Reference/Reference.html).
