Parents and Children Tasks Not Stacking Correctly

Hi all,

I recently inherited a completely broken Gantt Chart from a developer who quit. Has anyone seen this before? I don’t really know where to begin looking. No Tasks or Parents are stacking correctly, they are all on the same level. I’d be happy to share code with anyone privately.

We are using an ASP MVC project, and the custom JavaScript is in a standalone razor file.



There is no possibility to help using only attached screenshot. Please, provide with complete demo where the problem can be reproduced.
Please check if the duration was set in the data.

Also you can read documentation and check samples for understanding how to start work with Gantt Chart. … _init.html

check the value of gantt.config.columns config

Probably this property is missing from your config, e.g. see what happens when I disable it in basic sample:
