ScrollRect and Vertical layout group move to top

I want to top list move to top position. I use stationABuildingScroll.verticalNormalizedPosition = 1f; but it’s not work because content size filter.

Try using transform.SetSiblingIndex(0). The layout groups order their children by the sibling index, so that should move it to the top, I think.

Are you trying to change the order of the children or are you trying to scroll the scroll rect?

I think it’s can’t change order of the children because when I press the button building the box it’s set active = false. I am not sure about scroll the scroll rect. Can you suggest me ?
