Adding image to grid excell type "combo"

Hi ,
I want to be able to add images to the select items in the “combo” eXcell type for a grid.
How may i go about doing this?

Does setting eXcell type to “combo” , make the cell contain a dhtmlxCombo.
If yes, i am not able to use combo.addOption().
I can only use combo.addOption(option, text, css).

Please help.

It not possible without code modifications.

Yes, “combo” eXcell type is an instance of dhtmlxCombo object.

i am not able to use combo.addOption().
Following code works correctly at local example:

mygrid.loadXML("../common/combo.xml",function(){ var combo=mygrid.getColumnCombo(0); combo.addOption([["one","!!!one",""],["two","!!!two",""],["three","!!!three",""]]); });
