Hi,
I have the following situation:
There's a parent task with 4 child tasks without dependencies to one another. Each child task has its own start and end date. If I drag the parent task a week further, the child tasks will move with it but due to earlyStartDate (if I'm not mistaken) they will all get the earliest start date possible and thereby ignoring their old "hierarchie":
Is it possible to disable this functionality, so I would end up with this:
I've tried setting manuallyScheduled to true on the child tasks, but that blocks moving the parent task.
Thanks!

Hi!
Gantt has no such functionality yet.
I can suggest you to use your own model and override setStartDate method with your custom logic to update children tasks .

class MyModel extends TaskModel {
...
setStartDate(date, keepDuration) {
// Your custom logic goes here
super.setStartDate(date, keepDuration);
}
}
const project = window.project = new ProjectModel({
taskModelClass : MyModel,
...
});
