The React Tree View is a graphical user interface component that to represents hierarchical data in a tree structure. It provides great performance with its advanced features like load on demand, checkbox support, multiple selection, tree navigation, drag and drop, tree node editing, and template support.
Bind data to the Tree View component from any valid data source, such as XML, JSON, and JSONP. The tree data can be local or remote data and fetched using different kinds of adaptors like OData, OData V4, URL, JSON, and Web API.
This component has a load-on-demand (lazy load) option that allows you to load huge amounts of data dynamically, which improves the control’s performance.
Also, child nodes in the control can be loaded from any web services or inserted dynamically.
Display nodes with labels and icons to present the content in a more readable format. This is helpful in making a typical directory tree and file system.
It provides built-in support for checkboxes, allowing users to select more than one item. The tree view checkbox has a tri-state mode also, which is applicable only for parent nodes. In this mode, the parent node will go into the indeterminate state when the child nodes are partially checked.
Nodes can be dragged and dropped at all levels of the same TreeView.
Tree nodes can be dragged and dropped from one parent node to another within the same level or at different levels.
Extending the drop behavior allows users to drop tree nodes from one tree view to another.
Drop tree nodes to any external container or component by extending the tree view node drop action.
Allows users to select multiple nodes. When the drag-and-drop feature is enabled, all the selected nodes can be dragged at the same time.
Edit the tree nodes’ label text on the client side by double-clicking it. When editing tree view nodes, the tree view data source will also be updated with the modified data.
Render the tree view nodes in the ascending or descending order based on the label text for improved readability.
The TreeView component can be customized through its node template support, which allows defining a custom structure for tree nodes. You can use node templates specifically for parent nodes, child nodes, or both, and include images and any custom element structure.
Easily customize the expand and collapse icons based on the requirement of your application.
It supports tooltips for tree nodes that display information about the nodes while hovering over them. You can bind a tooltip from a data source along with node fields.
A context menu can be integrated with the TreeView component to open when a node is right-clicked. The menu helps users perform node manipulations such as adding, removing, and renaming nodes.
A node’s text wraps when it reaches edge of the TreeView. The node’s height will be adjusted automatically based on the content.
Supports right-to-left (RTL) direction for users working with right-to-left languages like Hebrew, Arabic, or Persian.
It allows you to customize the tree nodes by level. For example, apply specific styles to leaf nodes, first child nodes, and second level nodes, etc.
You can add validation to the tree node’s text on editing like required, a minimum or maximum length, etc.
Several built-in SASS-based themes are available such as Tailwind CSS, Bootstrap 5, Bootstrap 4, Bootstrap, Material, Fabric, and High Contrast. Simplify theme customization either by overriding the existing SASS styling or creating custom themes by using the Theme Studio application.
The React TreeView component has a rich set of developer-friendly APIs to control all UI elements and behaviors, allowing you to provide the best experience to your end users.
Easily get started with the React TreeView using a few simple lines of TSX code as demonstrated below. Also explore our React TreeView Example that shows you how to render and configure the Treeview in React.

You can find our React Tree View demo, which demonstrates how to render and configure TreeView.
No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.
A good place to start would be our comprehensive getting started documentation.
