For various Agile teams, grouping issues together based on parent task or other matching criteria is very important. For example, grouping all technical tasks belonging to a story is quite common. But each team has its unique issue data, workflow conditions, and prioritization behavior.
While working on the work/task board, we have grouped or categorized the issues together in a vertical way based on issue status. Each column groups issues having the same status or equal to statuses defined for the column.
To be able to group issues in a horizontal way, GreenHopper provides additional functionality of a Swimlane. A Swimlane is a categorization of issues in a horizontal way on task board.
To access Swimlane settings, open the Tools action under your team board and click on Configure. Then, go to the Swimlanes tab.
As shown in the preceding screenshot, you have the following options available to configure Swimlanes.
