Hi Tony
I don't know how to implement but.. using 2 grids without frozencols, fist grid have 1 or 2 cols that will be the 'fixed'
Second grid have dozens of cols but none frozed, then it seems to be the same grid, secon have horizontal scroll bar but it don't alter first grid.
It seems to be frozen cols because cols on first grid are always visible.
This have some limitation (sort, filter, etc…) but lets me edit the second grid.
My problem is how to syncronize both vertical scrolls.
