Gantt constraint with start in percentage of parent like ms project

Hello,

in MS project you can set a constraint to autoshedule a new task with percentage of the duration of the parent task or with number of days after a child task should start in realationship to the parent task.

example 1:

parent >>> starts today with duration 6 days

child should start 50% after the parent duration <<<< today + 3 days

example 2:
parent >>> starts today with duration 6 days

child should start 4 days after parent <<<< today + 4 days

So my question is, is there actual a functionality in dhtmlx gantt (we have the current commercial version of it) or how should it be implemented? With a startup sequence which recalculate when data is loaded?

Hello Marcel,
There is no built-in feature, you need to implement a custom solution by using Gantt API and Javascript.

The following example can help you to start:
