How far have you got? What *specifically* is the problem you're facing? The Xcode object library provides the Disclosure Triangle Button, so that's the hard part out of the way. Once you've got one of these on a view, all you need is a method that detects when this button is pushed, and you can then take responsibility for showing and hiding the relevant view. — Paul Patterson, Dec 08 '14 at 11:21

Collapsing / expanding can be implemented by adjusting auto layout constraints in the action method of the disclosure triangle button.

@property (nonatomic, weak) IBOutlet NSLayoutConstraint *moreInfoBoxHeight;

[[self.moreInfoBoxHeight animator] setConstant:75];

The view at the picture given is NSOutlineView. It is the NSTableView subclass.
