Rows in grid may be grouped to categorize data. Each group may be expanded or collapsed to control the amount of information shown for a particular category.

Grouping in grid is done by inserting the <group> tag; the scope of a declared group starts from the row immediate after the group tag to the beginning of following group tag. Groupings can be made without visible distinction by leaving out the labels in the group tags. A visible grouping can be collapsed by clicking on the small expansion button next to its label.
