I have a question. I used the job splitting attribute. However, if the schedule overlaps as shown in the image, the tasks overlap. Is there a good way to differentiate between overlapping tasks?
That feature would at least creating different heights for the task rows. For now, there is no good way for that. In the 7.1 version, the dev team will add a way to set different heights for the task rows, so, you will be able to implement a solution to show overlapping tasks in a different position.
I have the following snippets where Gantt modifies the appearance of overlapping tasks. That can help you in creating a custom solution.
