Folders: Sharing boards with user groups
Folders can be created in the dashboard - with the create folder option. You can place any number of boards in a folder.
When a folder is shared with a user or a number of them - they automatically gain access to all of the boards within this folder. This is a great way to control which teams within an organization have access to what sets or types of projects.
If you’re using the Enterprise service plan, you can take advantage of a built-in user groups feature. Learn more about it here.
