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

This article explains how to prevent nodes from moving outside the lane in Vue Diagram. In the Syncfusion® Vue 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: 'Nodee 1'} ],
              margin: { left: 60, top: 30 },
              height: 40, width: 100, ports: port,
              constraints: NodeConstraints.Default |NodeConstraints.AllowMovingOutsideLane
           },
         ]
