New eXcell that combines eXcell_tree with eXcell_combo

I need some guidance on trying to make a new eXcell. I want to have the tree behavior but use the dhtmlxcombo as the editor.

I have read the eXcell documentation and the various eXcell_*.js source files, but it is not clear how one would accomplish this. Can you provide some guidance if this possible? And, maybe an example?

Best regards,


Please contact and provide detailed requirement what shuould costom excell do.
