Gantt sheduler react

Hii,
how can I get all the id’s of the child from a parent node

Hello,

If you want to get the DOM elements of the child tasks, you can get the IDs of the children by getChildren method and use getTaskNode to return the HTML element of the task bar:
https://docs.dhtmlx.com/gantt/api__gantt_getchildren.html ;
https://docs.dhtmlx.com/gantt/api__gantt_gettasknode.html ;
or getTaskRowNode to return the HTML element of the task row in the table:
https://docs.dhtmlx.com/gantt/api__gantt_gettaskrownode.html ;
If you need to get the IDs of 1st-level child tasks, then you can use getChildren method.
Please check the example:

If you need to get the IDs of children of all levels, then you need to use eachTask method:
