Nested Scroll Tile Returns

Nested scroll functionality reintroduced to enable layered scrolling compositions for richer interactive layouts

1. Purpose & Scope

This article documents the return of Nested Scroll Tile functionality in Tiled v52.0.0. A scroll tile placed inside another scroll tile creates a layered scrolling composition where each container scrolls independently within its own boundary.

Scope: All Tiled users with Builder 2.0 access (Editor and above) building complex multi-axis scroll layouts.

2. Feature Description

Independent Scroll Axes

Inner and outer scroll containers can have different directions (e.g., outer vertical, inner horizontal). Each axis is controlled independently by the viewer.

Layered Compositions

Enables design patterns like: a horizontal product carousel within a vertical narrative page; a fixed sidebar with independently scrolling content panels; multi-panel dashboards with independent data sections.

Builder 2.0 Only

Nested Scroll Tile is a Builder 2.0 feature. Builder 1.0 nested scroll behavior is not affected.

Scroll Direction Fix

The horizontal automatic direction detection fix (Bug Fix Bulletin KB-v52-04) ships in the same release and is a prerequisite for reliable nested scroll behavior in complex multi-axis layouts.
