Grid View with grid_view_sorting_order=topological does not reflect true topological order #56575
Description
Apache Airflow version
3.1.0
If "Other Airflow 2/3 version" selected, which one?
No response
What happened?
Webserver setting: AIRFLOW__WEBSERVER__GRID_VIEW_SORTING_ORDER=topological
DAG structure: multi-level DAG using @task_group
Even when the configuration option grid_view_sorting_order=topological is set, the vertical order of tasks and task groups in Grid View does not match the actual topological (execution) order of the DAG.
The Graph View and execution dependencies are correct, but the Grid View’s left-hand task list appears to be sorted alphabetically by task_id / group_id.
Example DAG structure:
start >> step_a >> step_b >> finish
Expected topological order (execution order):
start → step_a → step_b → finish
Actual order shown in Grid View:
finish
start
step_a
step_b
Expected Behavior
When grid_view_sorting_order=topological is used,
the vertical task order in Grid View should match the DAG’s topological execution order.
Expected display:
start
step_a
step_b
finish
Grid View appears to sort sibling tasks/groups alphabetically rather than following topological order.
Graph View and runtime behavior are correct; only the Grid View ordering is inconsistent.
What you think should happen instead?

How to reproduce
Create a simple DAG:
start >> step_a >> step_b >> finish
Set environment variable:
AIRFLOW__WEBSERVER__GRID_VIEW_SORTING_ORDER=topological
Run the DAG and open Grid View.
Observe that the left-hand task list does not follow topological order.
