+			If [code]true[/code], this [CanvasItem] and its [CanvasItem] child nodes are sorted according to the Y position. Nodes with a lower Y position are drawn before those with a higher Y position. If [code]false[/code], Y-sorting is disabled.
 			You can nest nodes with Y-sorting. Child Y-sorted nodes are sorted in the same space as the parent Y-sort. This feature allows you to organize a scene better or divide it into multiple ones without changing your scene tree.
