enables the auto scheduling mode, in which tasks will always be rescheduled to the earliest possible date
Available only in PRO Edition
gantt.config.auto_scheduling_strict = true; gantt.init("gantt_here");
This functionality is available in the PRO edition only.
This config is defined in the ext/dhtmlxgantt_auto_scheduling.js extension, so you need to include it on the page. Read the details in the Auto Scheduling article.
Note that starting from v6.1 the config works only when the auto_scheduling_compatibility option is enabled.
By default, tasks are rescheduled only when a new date violates the constraint.
