Description
The Telerik UI for ASP.NET Core DropDownTree combines the functionality of a DropDownList and a TreeView component. It is an editor of hierarchical data in a tree-like structure with an option to select one or more items, filter items, and customize its nodes.
The DropDownTree offers built-in checkbox support, keyboard navigation, and RTL support, and provides templates for complete customization of each node. You can bind the component to various data sources and take advantage of its load on demand feature to request data only when a parent node is expanded.
The current demo shows an example of a DropDownTree whose items are defined within the helper declaration.
