Data Grid - Collapsible Columns
Collapsible Column Groups is a part of the multi-column headers feature that provides a way to collapse or expand a column group to show a smaller set of data. This sample has three multi-column header columns with collapsible groups. "Company Information" and "Phone Information" have two levels, while "Address Information" has three levels.
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
