Another Update:

Collapsible groups
Groups can be made collapsible by adding either collapse="open" or collapse="closed" to the group tag. This will make the group header row clickable (to expand and collapse the group), and the group will initially start open or closed, respectively.

Note: a header row containing content must immediately follow the group tag for this to work.
