Hi there, you have a sample of linked tasks here (https://docs.dhtmlx.com/gantt/samples/02_extensions/18_linked_tasks.html) that works fine with the Material Theme. However, I tried to apply that to my project that uses the standard one and it did not work properly. So what I did was to copy the code of your example, above, and create a snippet (https://snippet.dhtmlx.com/e9jl5ccp) to try to reproduce that to see if the problem was on my project, but I found out that it didn’t work on the snippet either. When I say did not work I mean it is not highlighting the connected tasks.
Thanks

Hello Pedro,
You need to include the styles to see the red color for the lnked tasks. Here is the updated snippet:
