This is a toggle command consisting of two states:
Enable Grouping
Select to show the Grouping area and enable the feature to be used. When the EDE is first opened during a session, the Grouping area is enabled by default.
Cancel Grouping
Select to hide the Grouping area and cancel any current grouping of the data. When canceled, the Grouping area remains hidden even if you select a different item type to display in the EDE.
