Creating collections for Business Class teams
With Business Class, you have the ability to create Collections to easily group boards together. We recommend creating collections by team, department or even major project.
Creating a new collection
To create a new collection, you'll first want to go to the boards page for your team at https://trello.com/[your-team-name-here]
From there, click "Create a Collection" on the left side:
Adding a board to a collection
On your team's boards page, click the "+" below any board and then choose the collection you'd like to add the board to. To remove it, click the "+" again and click the collection name to uncheck it.
Editing or deleting a collection
You can edit or delete an existing collection from the menu under each board. Click the "+", then the pencil next to the collection you'd like to edit or delete.
