A Boolean value indicating whether VoiceOver should group together the elements that are children of the receiver, regardless of their positions on the screen.
The default value for this property is NO.
For example, consider an app that shows items in vertical columns. Normally, VoiceOver would navigate through these items in horizontal rows. Setting the value of this property to YES on the parent view of the items in the vertical columns causes VoiceOver to respect the app’s grouping and navigate them correctly.
