is it possible to have “independent” time frame for the tasks, even if they are in parent-child relationship with subtasks? What I want to do is, to set the time frame for the parent items independently from its children.
There is no built-in way to let subtasks of the project get out of the project bounds. A project task is a task that starts, when its earliest child task starts, and ends, when its latest child ends:
Task Types Gantt Docs ;
As a workaround, you can add a task with the
task type and make it look like the project task, so it will have its own start and end dates.
You can return the
gantt_project CSS class in the
task_class template if the task has subtasks:
task_class Gantt Docs ;
Please check the example of how it might be implemented:
