I want to search work and its parent in fixed columns

Is there a way to search a task and its parent in a grid with fixed columns?
I want to implement by merging a grid with a fixed column and a grid with a search function. (in gantt)

Hello,
To add fixed/frozen columns in the grid, you need to actually create several grid views and add column configuration for each grid:
https://docs.dhtmlx.com/gantt/desktop__layout_config.html#configsandtemplatesofviews
However, with that approach, inline editors and some other things may not work correctly in both grids.
It will be fixed in the future, but I cannot give you any ETA.

However, here is the snippet with the fixed grid and the filter functionality:
