Fields
| Name | Value | Description |
|---|---|---|
| None | 0 | No edge pinning. The viewport stays at its current scroll position regardless of item changes. |
| Beginning | 1 | Pins the viewport to the beginning of the list. When the user is at or near the top and new items arrive at the beginning, the viewport stays at the top showing the newest items — matching standard news feed / notification list UX. |
| End | 2 | Pins the viewport to the end of the list. When the user is at or near the bottom and new items arrive at the end, the viewport auto-scrolls to show them. If the user has scrolled away, auto-scroll disengages until they return to the bottom — matching standard chat / log UX. |
