Treegrid filter view children

Is there a way or do you have it planned for the future so that the children can be seen when it is filtered in the header?
For example, DHTMLX - TreeGrid. Custom filter in the header

If I filter for Gary Ortiz, the rows for “Real State”, “Trip Planner” and “Education System” can be displayed.

Thank you

Unfortunately such filtering mechanics for the in-header filters is not planning to be added for now.
I can only suggest you to use a data.filter() method with a custom filtering function:
