Setting multiline nodes for html initialized tree

I have this dhtmlxTree. I’d like to remove horizontal scrolling. Seems like the way to get this is to have multiline for the nodes. How do I specify multiline for this HTML initialized tree?

[code]

[/code]

+---+ | +--This is a long line of text that I would like to have on multi lines.

+---+ | +--This is a long line of text that I would like to have on multi lines.

Any clues?

Initilize from list
