You can group related dashboards using dashboard tags. To do so, go to “Dashboard”, click on the gear icon to edit it, then on the section “Tags” create a new tag. After that, on the section “Group dashboards using Tags” select the grouping tag.
To create sub-levels you just need to repeat the above procedure for each level. It is possible to create three grouping levels.
After this, the dashboard will be grouped in the sidebar. The grouping criteria uses the key and value. If you delete a tag and that grouping has sub levels, the sub-levels will be removed as well.
When you share a grouped dashboard the grouping will be shown on the shared account’s list of dashboards.
