The Angular TreeView is a graphical user interface component that represents hierarchical data in a tree structure. It provides great performance with its advanced features like load on demand, check boxes, multiple selection, tree navigation, drag and drop, tree node editing, and template support.
Bind data to the TreeView 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.
The Angular TreeView component has a load-on-demand 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 service 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.
The Angular TreeView component provides built-in support for check boxes, allowing users to select more than one item.
The TreeView check boxes also have a tri-state mode, 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.
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 treeview to another.
Drop tree nodes to any external container or component by extending the angular treeview node drop action.
The Angular TreeView component 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 treeview nodes, the treeview data source will also be updated with the modified data.
Render the TreeView nodes in the ascending or descending order based on the label text for improved readability.
The Angular TreeView component can be customized through its node template support, which allows you to define 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.
Angular TreeView supports right-to-left (RTL) direction rendering for users working with right-to-left languages like Hebrew, Arabic, or Persian.
The Angular TreeView component with rich UI provides animation support when expanding or collapsing the TreeView nodes.
Easily get started with the Angular TreeView using a few simple lines of HTML and TSX code as demonstrated below. Also explore our Angular TreeView Example that shows you how to render and configure the treeview.

public field:Object ={ dataSource: this.hierarchicalData, id: 'id', text: 'name', child: 'subChild' };TreeView is also available in Blazor, React, Vue, and JavaScript frameworks. Check out the different TreeView platforms from the links below,
With continuous improvement in Angular versions, the Angular TreeView is kept up to date to make it compatible with versions starting from 4 to the latest version.
The TreeView component for Angular 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.
We do not sell the Angular TreeView separately. It is only available for purchase as part of the Syncfusion Angular suite, which contains over 70 Angular components, including the TreeView. A single developer license for the Syncfusion Essential Studio for Angular suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
You can find our Angular TreeView demo here.
No, our 70 Angular components, including TreeView, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their tree view alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 70 Angular components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
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.
