In absolute layout i add three panels, one after another but now the end of the visible page is reached but there is no scroller to see the last panel.
So how can i design forms longer than the visible area??
I think the initial size for the composition root (absolute layout) in the visual editor is 100% x 100%, so that might be the reason the last one gets cut off. Try setting the root component to undefined height or to some explicit pixel height.
