The grouping feature is used to determine which records that are displayed, and makes it possible to work with a subset of the database (for example, albums released by a specific artist).
Using the grouping feature is similar to using a filter, except that it is easier to change the value used in the filtering process. For example, if you group by artist, you can simply select another artist to display the albums released by this artist (if you used a filter you would have to modify the filter to get the same result).
The first item in the list represents the open database. Select this item to display all records in the table.
You select grouping definition from the drop-down above the grouping list.
You can also manage the grouping definitions in the active view by choosing Grouping Definitions from the View menu. Here you can both add, edit and delete grouping definitions.
