Table fields with a drop-down list or a limited set of possible values are automatically grouped together when sorting the column.
Using Shift+Click on groups works in the following way:
- On field headers - accumulates sorts and groups.
- On a field already grouped - changes the sort order within that group.
- While opening or closing a group header - closes all the group headers at that level or below.
When switching groupings, the group(s) for the currently selected record automatically opens, with all others closed.
Click the +/- button to view or hide the groups.
