Tree display formatting

[Klaudia_Korejwo]

Hi there,

Does anyone know if it's possible to get rid of these lines on the left at each row? I'm using a tree component.

in the advanced stylesheet

.cross-alignment{
	visibility:hidden;
}

I am however not sure what other things cross-alignment could affect.

The lines that show the organization of the tree? Why would you want that?
