Card Relations in the Gantt Chart View

It is possible to add relations to cards in KanBo. These relations will be clearly visible on a Gantt chart view. Cards can be connected in the following relations:

Card relations are time dependent connections. In the case of the previous-next relation, it seems obvious, but the parent-child one also has a certain time principle.

Parent and child relation

Parent card is the main card while the child card can be understood as a subcard. Therefore, child card must be started and completed in the “lifetime” of the parent card.

The parent-child relation can be shown in two ways:

  1. Hidden – only parent card is visible with  indicator showing that there is at least one child 
  1. Extended – a group of card with grey highlight

You can expand the parent card to see its children. Card relations can be complex. Gantt chart enables you to see it clearly.

The complexity of parent and child relations is worth to be visualized in the Mind map view. You can manage this relations there.

Previous and next relation

Adding the card relation

The previous-next relation is indicated by arrow and a line between 2 cards. You can use the mouse to draw lines between cards and setting the previous-next relations.

  1. Hover over a card.

Two big dots on the card sides will appear. Decide if you want this card to be the previous or the next in relation. In the example below Windfarm card will be the previous to the Hydropower card.

  1. Drag a dot and link it to the another card.

Removing the card relation

Just click the line between cards to remove their relation.

Relation will be deleted permanently.
