Card Types

In this article:

Overview

In KanBo, cards are the fundamental units of work. They represent tasks, projects, ideas, or any actionable items. To support different collaboration scenarios, KanBo offers several card types, each tailored to specific needs and contexts. Understanding these card types helps users build flexible, connected spaces with minimal duplication and improved visibility.

Card types:

  • Standard cards – independent tasks (cards without parent card)
  • Subcards – cards that have parent cards 
  • Archived cards – cards that are no longer active
  • Mirror cards – cards that are mirrored from other spaces
  • Space cards – a special type of card, that allows you to represent the entire space in the form of a pie chart

All of these card types can be enabled or disabled in the space display settings.

Standard cards

Standard cards are the default and most commonly used card type in KanBo. They represent an independent task. That is, they have no parent cards, but can be related to other cards in the rest of the card relation types.

Example: Standard card can have subcards but have no parent cards.

Subcards

Subcards are cards that are hierarchically linked to a parent card. They represent smaller pieces of a larger task and help organize work into manageable steps. Subcards behave in space exactly like standard cards.

Example: The subcard Picnic Lectures has the Urban Picnic parent card.

Mirror cards

Mirror cards are linked duplicates of existing cards. Any updates made to a mirror card are synchronized with the original, making them ideal for cross-board visibility and collaboration. Mirror cards cannot use all the features of guest space.

Example: The Urban Picnic card in Guest Space is a mirror card.

Space cards

Space cards allow you to represent entire spaces in the form of cards. This way you can visualize the summary of a particular space and then manage it just like a regular card.

Example: The Green Week space as a space card.

Archived cards

Archived cards are inactive cards that are no longer part of the current workflow and cannot be edited. Archived cards can be restored.

Example: The Urban Picnic card after archiving.
