The list view allows you to view your rows grouped in sections based on common data. You can group together any row based on any column. To group rows by specific criteria.
Click on the GROUP icon on the toolbar which opens this dialog to set the groups.
A small grey header area will appear at the top of the list. You can now drag columns directly into this grey area to set the group by option. You can drag multiple columns to set multiple group conditions.
You can quickly expand or collapse the group sections by using the right clicking on the list view and choosing Expand All and Collapse All. These two options are only shown when grouping is on.
