atul-astronomer opened a new issue, #63727: URL: https://github.com/apache/airflow/issues/63727
### Apache Airflow version 3.1.8 ### If "Other Airflow 3 version" selected, which one? _No response_ ### What happened? Gantt view is not scrollable when there are many tasks that user needs to scroll and see all the tasks https://github.com/user-attachments/assets/21bb1250-90f3-49c9-9e77-a5bde486ac09 ### What you think should happen instead? _No response_ ### How to reproduce Use the below Dag to reproduce the issue. Trigger the Dag, exapnd all the task groups and notice task list is scrollable but not the gantt view. ```python from airflow.sdk import DAG from airflow.decorators import task from airflow.providers.standard.operators.empty import EmptyOperator from airflow.utils.task_group import TaskGroup from datetime import datetime from dataclasses import dataclass from dataclasses_json import dataclass_json from random import seed, randint @dataclass_json @dataclass class Payload: seed: int a: str b: str c: str d: str def make(i): return Payload( seed=i, a=str(i) * 5, b=str(i) * 10, c=str(i) * 15, d=str(i) * 20 ) def transform(self): self.a = str(int(int(self.a) / 5)) self.b = str(int(int(self.a) / 10)) self.c = str(int(int(self.a) / 15)) self.d = str(int(int(self.a) / 20)) @task def mk_payloads(i): return [Payload.make(j).to_dict() for j in range(1, i)] @task def transform(_payload): payload = Payload.from_dict(_payload) payload.transform() return payload.to_dict() @task def check_transformed(_payload): payload: Payload = Payload.from_dict(_payload) orig = Payload.make(payload.seed) orig.transform() # same transformation made to same data # results should be same, otherwise something got lost along the way assert orig == payload minmax_map_indices_per_lane = (5, 60) lanes = 10 with DAG( dag_id="many_expand", schedule=None, start_date=datetime(1970, 1, 1), catchup=False,tags=["taskmap"] ) as dag: seed(42) # be deterministic for i in range(lanes): with TaskGroup(group_id=f"lane{i+1}"): min_map, max_map = minmax_map_indices_per_lane mapped = randint(min_map, max_map) check_transformed.expand( _payload=transform.expand(_payload=mk_payloads(mapped)) ) ``` ### Operating System Linux ### Versions of Apache Airflow Providers _No response_ ### Deployment Other ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
