Space tags
When adding a tag to a card you can select from the list of existing tag, or create a new one. When you create a new tag, that tag is created on a per Space basis. For example, if I create a tag ‘Blog Post’ on a card in the ‘Marketing’ space, that tag will only be available within the ‘Marketing’ space. This prevents irrelevant tags spilling over to other teams boards and workflows.If you move a card to a different space, only the tags that are in use by both spaces will be preserved on the card.
