The TreeView component allows you to customize the look of TreeView nodes by using the nodeTemplate property. This property accepts either template string or HTML element ID.

In the following sample, employee information such as employee photo, name, and designation have been included using the nodeTemplate property.

The template expression should be provided inside the ${...} interpolation syntax.
