This ASP.NET Core TreeView example demonstrates the template functionalities of the TreeView. Select the root node by clicking on it, or expand the root node and select the customized child node.
The TreeView component has an option to customize the node structure through the nodeTemplate property, so that the tree node can be formed with any custom structure.
In this demo, the node is formed with the employee's image, name and designation.
