Hi Andrei,
Greetings from Syncfusion support.
Currently, we do not have support for rendering multiple taskbars in the project view. However, we have already logged a feature report for it. You can track its status from the below feedback link.
As we have already lined up some major features, we could not implement this support immediately. We will implement this and include it in any of our upcoming releases. Please cast your vote on this feature. We will prioritize the features in our upcoming roadmap based on customer demands.
Please contact us if you require any further assistance.
Regards,
Monisha.
