To create a new group, use the Group button (the icon) in the Toolbox.
You can combine dashboard items into a group in several ways.
A dashboard item group cannot be added to another group.
The dashboard item group provides the capability to manage interaction between dashboard items within and outside the group.
The Master Filter option allows you to specify whether the current group allows you to filter external dashboard items using master filter items contained within the group. If this option is disabled, master filter items contained within the group can filter only dashboard items from this group.
The Ignore Master Filters option allows you to isolate dashboard items contained within the group from being filtered using external master filter items.
The default group behaves opposite to the default tab page. While the group isolates filter items from the outside, the tab page does not change the item's data interactivity behavior.
To access interactivity settings for the dashboard item group in code, use the GroupItem.interactivityOptions property. This property returns the DashboardItemGroupInteractivityOptions object that exposes the following members:
Gets or sets whether the current dashboard item ignores filtering applied by master filters.

The following code sample shows how to add an empty group:
var groupItem1 = new DevExpress.Dashboard.Model.GroupItem(); dashboardControl.dashboard().groups.push(groupItem1); dashboardControl.dashboard().rebuildLayout();
