How to Prevent Node Moving Outside the Lane in React Diagram?

In the Syncfusion® React Diagram you can manage the movement of nodes using Node Constraints, particularly to prevent nodes from moving outside designated lanes.

To restrict a node’s movement to only within its assigned lane, you can use the AllowMovingOutsideLane option in the node constraints. When this option is enabled, it ensures that the node can only be moved within the confines of the lane, preventing any unwanted positioning outside of it.

// set constraints as  AllowMovingOutsideLane for node 
constraints: NodeConstraints.Default | NodeConstraints.AllowMovingOutsideLane 

set the constraints for the following Child node

children: [
   {
       id: 'node1',
       annotations: [{ content: 'Node 1' }],
       margin: { left: 60, top: 30 },
       height: 40, width: 100, ports: port,
       constraints: NodeConstraints.Default | NodeConstraints.AllowMovingOutsideLane
   },
], 

You can find a working example of this implementation in the provided sample on StackBlitz.
