Turn off sorting in Multirow header

In the case when we have multirow header like in following example:
dhtmlx.com/docs/products/dhtmlxG … eader.html

Is it possible to keep the sorting available for only first row? So, if a user has a second row of headers the sorting will not happen when it’s clicked.

Please Advise.

Actually I found the answer on the forum.

dhtmlxEvent(mygrid.hdr.rows[2], “click”, function(e){ e.cancelBubble = true; })

mygrid.hdr.rows[2], “click”, function(e){ e.cancelBubble = true; };
