How to Render Tree with Collapsed Child Nodes in Angular Diagram?

In our Syncfusion® Angular 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.

app.component.ts

public getNodeDefaults(node: NodeModel): NodeModel{
// Setting isExpand False
   if (
     (node.data as any).Name === 'node12' ||
     (node.data as any).Name === 'node27'
   ) {
     node.isExpanded = false;
   }
   return node;
}
