allows or forbids creating links from parent tasks (projects) to their children
The property has been deprecated in v9.1, use the descendant_links property of auto_scheduling instead.
Available only in PRO Edition
gantt.config.auto_scheduling_descendant_links = true;
gantt.init("gantt_here");
This functionality is available in the PRO edition only.
This config is defined in the auto_scheduling extension, so you need to activate the auto_scheduling plugin. Read the details in the Auto Scheduling article.
By default, links from parent tasks (projects) to their children can't be created.
