Drop down view in cocoa

Question

I'm looking to create a 'drop down' view that falls in front of the main window. An example of this would be the window that drops down when you click 'Advanced' in System Preferences->Networking.

If someone could point me in the right direction documentation-wise that would be great. Thanks in advance.

Answer 1

That's called a sheet. Here's a quick introduction and the Apple documentation.
