Is there any basic documentation like a "Collection View

No, not currently. It's a known issue and is being tracked.
And even if you get the basics working, there is still a lot of issues
with it, in particular when using resizing NSCollectionViewItems (e.g.
rdar://5950467 "NSCollectionView does not work correctly with
NSScrollView's autohideScrollers", rdar://5962073 "NSCollectionView
resizes its item-views incorrectly" (during live-resize) or worst of
all rdar://5962086 "NSCollectionView scrolls to origin on
resize" (supposedly a dup of rdar://4867132 which *really* should've
been fixed by now) which makes one of my apps nearly unusable). Each
of these are trivial to reproduce, have simple example code available,
but seem to be collecting dust.
I'm not sure who decided it was ready to ship in 10.5, but I think it
was a bad call.
Incidentally, if any Apple engineers know a workaround for rdar://
5962086, it'd be well appreciated. I looked at nearly all the message
sends going on between the NSCollectionView and the NSScrollView but
could not devise a way to prevent it from scrolling back to the origin.
Daniel.
