Multiple rows dhtmlxgrid

Hi, we are using dhtmlx grid that a dataset has a row this exising dhtmlx.
I want to know one dataset which is a row would show two rows in the grid.
I find your website which part is support there have Multiple rows information, but I think is what I am looking for it.
I would like to know how to resolve this case, please let me know if you have a information. Thank you.

Unfortunately such feature is not available.
You may try to use the colspan/rowspan in your grid, subrow or the treegrid functionality.
