| Absolute | Same as Sandbox.UI.PositionMode.Relative, but the elements size does not affect other elements at all. |
| Relative | Enables <c>top</c>, <c>right</c>, <c>bottom</c>, <c>left</c>, and <c>z-index</c> to offset the element from its would-be position with Sandbox.UI.PositionMode.Static. |
| Static | Default, the <c>top</c>, <c>right</c>, <c>bottom</c>, <c>left</c>, and <c>z-index</c> properties have no effect. |
