Create parent/child filter groups
Parent/child filter groups are sets of related filters that let the user narrow down a set of results based on a logical hierarchy of sets and subsets, such as geography or time. Filter groups are supported for standard filters only, not for embedded filters.
Note: Only list filters can be added to a filter group.
When you add a filter to a filter group, Dashboards creates a copy of the original filter. Because the filters in a filter group are copies, you can make changes to a filter in a group without affecting the original filter outside the group.
