Frozen columns with filters

I am having a grid where I am already having header filters for all the columns.
Now I need to fix the first n number of columns. I tried to user splitat(n) but it gives following java script error in dhtmlxgrid_splt.js.
Error: ‘this._fake.hdr.rows[…].scrollHeight’ is null or not an object

If I remove header filters then frozen columns work fine but subrid in one of the frozen columns does not expand.

Please let me know if there is a way to use filters,frozen columns and subgrid altogather.

Thanks in advance. :slight_smile:

a) filters in split mode must work correctly - but you must call attachHeader command BEFORE splitAt. After applying split any modifications of header will fail

b) sub-row grid can’t be used in left part of splitted grid.
