I love having tasks summarized in one row and found this sample:
docs.dhtmlx.com/gantt/samples/04 … aying.html
It is also possible to add “task_id”, “” and element s on summarized tasks to enable dragging and resizing of summarized tasks.
However this all worked fine with previous versions of gantt control (until version 4.0.0). Can someone help me solve this to work with latest version of gantt control?
