Using the group role - Accessibility
the group role is used to identify a set of user interface objects which, in contrast with a region, are not intended to be included in a table of contents or a page summary (such as the structures that are dynamically created by a script or assistive technologies); a group should not be considered a major perceivable section on a page.
