Hi Sami,
Can you please elaborate your query?
Case 1: Rendering multiple taskbar in Project view.
In Project View, tasks are displayed in hierarchy manner. Currently we have support to render tasks with single schedule dates only. Do you want to render taskbar with multiple schedule. (i.e.) do you want to split the single task and render with different schedule dates in a row.
Case 2: Rendering multiple taskbar in Resource view.
In Resource view, when resources are assigned with multiple tasks, all the tasks should be displayed in a single row.
If you share us more details, in which case do you want to render multiple taskbars, we will share more details regarding that.
Regards,
Pooja K
