Description
Deck supports dependencies between cards, but these dependencies are currently not visualized in the Gantt view.
For example, if:
Requirements → Design → Development → Testing
are configured as dependent cards in Deck, the Gantt chart should visually show these relationships.
Requested functionality
Display dependencies between cards in the Gantt chart using dependency lines/arrows.
For example:
Requirements █████████
Design █████████
Development ███████████
The exact visual representation can follow the conventions of the underlying Gantt component, but the relationship should be clearly visible.
Expected behaviour
If Card B is configured as dependent on Card A:
the Gantt chart should draw a visual connection from Card A to Card B;
the connection should remain correct when the cards are moved or their dates change;
dependencies should work regardless of whether the cards are in the same Deck stack or different stacks, where supported by Deck's dependency model;
removing the dependency in Deck should remove the corresponding dependency visualization from the Gantt chart.
The dependency visualization should use the existing Deck dependency relationship rather than requiring users to configure the dependency a second time specifically for the Gantt view.
Rationale
Dependencies are an important part of project planning. A timeline showing only the dates and durations of tasks does not communicate which activities depend on others.
Deck already supports card dependencies, so the Gantt view should visualize the relationships that already exist in the Deck data model.
Without dependency visualization, users have to switch between the Kanban/card view and the Gantt view to understand the relationship between tasks.
Environment
Observed with:
Nextcloud 34.0.2 (Spring 26)
Deck 1.18.3
Current behaviour
Card dependencies can be configured in Deck, but no dependency lines/arrows are displayed in the Gantt view.
Desired behaviour
Visualize existing Deck card dependencies directly in the Gantt chart.
Additional implementation note
The Gantt implementation uses Frappe Gantt, which supports task dependencies. The Deck Gantt implementation currently appears not to pass the existing Deck dependency information to the Gantt task objects.
This feature should therefore ideally integrate the existing Deck dependency model with the dependency functionality of the Gantt component.
