Hello,
I am trying to create a sample where I want to show multiple life cycles of each project/task in one row itself. Is it possible? Can you please provide some sample?
Also, Is it possible to keep multiple milestones of tasks on top of each bars?

Thanks,
Surbhi

Hello @Surbhi_Agarwal,
Regarding this point:
I am trying to create a sample where I want to show multiple life cycles of each project/task in one row itself. Is it possible? Can you please provide some sample?
Yes, that’s possible with baselines functionality, that allows to create additional elements on the timeline area of gantt chart. You can read about it by the following links:
https://docs.dhtmlx.com/gantt/desktop__inbuilt_baselines.html
https://docs.dhtmlx.com/gantt/api__gantt_baselines_config.html
Here is an example:

In case if baselines flexibility won’t be enough to your purposes, you also can use the addTaskLayer
method, that also allows creating additional elements:

Regarding this point:

Yes, it’s possible to define multiple milestones for each task.
It can be done with built-in milestones:
https://docs.dhtmlx.com/gantt/desktop__milestones.html
Or with customized baselines(by adding additional CSS class to baseline):

Likely it will be the best option for your case.
Or you can create them with addTaskLayer
method, like follows:

So you can choose the most preferable approach.
