Property Value



True to enable the vertical scroll rail; otherwise, false. The default is true.


When content is scrolled without manipulating the scrollbar directly, for example, by touch, we call it panning. Because content can be both wider and taller than the display area, two-dimensional panning (horizontal and vertical) is often necessary. Rails improve the user experience in these cases by locking the panning to the axis of motion, either vertical or horizontal, as if the content were on a rail.

The following diagram demonstrates the concept of rails.
