Before you can group records by using the Group Panel, you must make it visible.
To show or hide the Group Panel, do either of the following:
Right-click anywhere in the grid, and then click Group > Group by Box.
This action will show the Group Panel
NOTE: Alternatively, you can make the Group Panel visible by configuring options in the Customize View window: Click View > Customize Views and select the Group by Box check box on the Options tab.
