How to Exclude Node from Layout and Position it in React Diagram?

This article explains how to exclude a node from the layout and position it in a React Diagram. In Syncfusion® React Diagram, when arranging nodes using a layout algorithm, there might be situations where you want certain nodes to be positioned manually rather than being automatically arranged by the algorithm. To achieve this, you can set the excludeFromLayout property to true for the nodes you wish to position manually. This will prevent the layout algorithm from affecting their placement.

To get started, you need to define the created event in the diagram, then set the excludeFromLayout property to true for each node you want to position manually.
Finally, specify the desired offset values for those nodes to control their exact placement.

created ={() => {
   for (var i = 0; i < diagramInstance.nodes.length; i++) {
       var node = diagramInstance.nodes[i];
       if ((node.data).Name === 'Robert') {
           // Excludes node from layout
           node.excludeFromLayout = true;
           node.offsetX = 150;
           node.offsetY = 150;
       }
   }
}}
