Dhtmlxgrid with show all sorting icon including attach header

Hi,
do we have a function to show all sorting icon including attach header by default after init?

For now, grid can show only one sorting icon at the time, it is by design

you can use setSortImgState API for that
https://docs.dhtmlx.com/api__link__dhtmlxtreegrid_setsortimgstate.html

We are plan to make this functionality more flexible in future.

You can assign a css class to grid, which will add an background image with sorting icon for all cells in the column, though.
