drawio-impl-swimlanes

What problem does it solve?

Swimlane diagrams in Draw.io are prone to misalignment when shapes use absolute page coordinates or when lanes do not behave as proper containers. This Skill enforces container-relative coordinates, supports horizontal and vertical lanes, nested lanes, and accurate header sizing to prevent cross-lane connection errors.

Core Features & Use Cases

• Enforces container-relative coordinates for all lane children to maintain layout integrity when lanes are moved.
• Supports horizontal and vertical lanes, nested sub-lanes, and header sizing to accommodate multi-line labels.
• Ensures cross-lane connections use the pool as the edge parent and that lane widths match the pool width for visual consistency.
• Useful for architecture diagrams, process flows, and multi-department diagrams where lanes represent functional areas.

Quick Start

Create a pool with container=1, add lanes with container=1, and place shapes with coordinates relative to the lane header.
