Parent and Child Card Relation

This post is also available in: Deutsch

Card relations are connections between different cards. These relations are designed to facilitate collaboration and enhance productivity by representing dependencies, associations, or hierarchical structures between various cards.

One of them is parent and child relation. This relation represents a hierarchical structure where a parent card is associated with one or more child cards. Child cards can represent subtasks, subprojects, or subtopics related to the parent card.

Card relations also work between different spaces. Child cards are not necessarily in the same space as their parent. Card relations are often used precisely to connect cards that are in different spaces together.

Complex relations

Cards can have complex relations. One card can have multiple parents and children at the same time. Cards in the parent and child relation are visualized with icons:

  • parent card
  • child card

Card relations are listed in the card view in the card details section. Below we can see the card relations details of the Photovoltaics card.

We can observe 3 cards connected together here. Solar power is the grandparent card of the Rooftop PV System card.

Children of the card are shown also in the child card group.

The child card is a subcard of the main task – the parent card. It means that the parent card is superior to the child card. Such a pair of cards has a certain time principle: the child card must always be started and completed in the “lifetime” of the parent card.

Parent and child relations are time-dependent. The child card must always be started and completed in the "lifetime" of the parent card.

Card relations are presented in different ways depending on the space view. See some examples here.

The example above shows four child cards of the Solar power parent card. They are presented as a card detail in a List view.


You can observe parent and child card relations in the Gantt Chart view and Mind Map view. There is also an option to expand child cards in the Kanban view and List view.

Even if the card has more than one parent, only one of them is the default parent. The connection visible on the Mind Map view is the one between the child card and the default parent card.
