Group Header

• Apr 01, 2021

Group headers display information about the corresponding group’s content. Commonly, a group header can show the group caption and the group image. Group headers enable end-users to expand and collapse groups. When a Side Bar View or the Navigation Pane View is used, end-users can click anywhere in the group header to expand the corresponding group. When an Explorer Bar View is used, groups can be expanded by end-users by clicking on the group expand buttons, located within group headers.

When the Navigation Pane View is applied, the expand button displayed within the active group header allows end-users to expand/collapse the Navigation Pane.
