How to Render Complex Tree With Collapsed Nodes in JavaScript Diagram?

In our Syncfusion® JavaScript 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

function getNodeDefaults(obj) {
if (obj.data.Name === 'node12' || obj.data.Name === 'node22') {
     obj.isExpanded = false;
   }
return obj;
}
