Gant chart with dropdown Projects

[ctrlaldelight]

I have this current view in my Gant chart (plugin is from Microsoft Gant 3.0.12.0)

Is there a way to structure it this way?

I used Gant Chart - xviz and managed to get these three levels, but I am unable to apply the different colours as in my previous chart.

Hi @ctrlaldelight 

You can do this using conditional formatting.
Open advanced Editor > Go to Conditional Formatting, select your task column, and choose your task.

I have attached the sample
