How to Render Complex Tree With Collapsed Child Node in React Diagram?

This article explains how to render a complex tree with collapsed child nodes in React Diagram. In our Syncfusion® React Diagram, layout nodes can be both expanded and collapsed. By default, child nodes are expanded. If you want to display a complex hierarchical tree with child nodes collapsed, set the parent node’s isExpanded property to false.

index.js

getNodeDefaults={(node) => {
         // Setting isExpanded to false
         if (node.data.Name === 'node12' || node.data.Name === 'node27') {
           node.isExpanded = false;
         }
         return node;
}
