I want to use the Gantt chart in my project. I checked the Day pilot angular Gantt tutorial. But it is without the menu and header. I want to add 3 or more headers and a menu in the left side header.
You can add custom row header columns using columns property:

The context menu can be added using contextMenuRow property:
