Angular TreeView | Hierarchical Data Model Tree List

Overview

Angular TreeView is a graphical user interface component that allows you to represent hierarchical data in a tree structure. It has great performance combined with advanced features like load on demand, check boxes, multiple selection, tree navigation, drag and drop, tree node editing, and template support.

Data binding

You can bind data to the TreeView component from any valid data source, such as XML, JSON, and JSONP. The tree data can be local or in any remote service and fetched using different kinds of adaptors like OData, OData V4, URL, JSON, and Web API.

Load on demand

The Angular TreeView component has a load-on-demand option that allows you to load huge amounts of data by dynamically loading the data on demand, which improves the control’s performance.

Also, child nodes in the control can be loaded from any web service or inserted dynamically.

Tree node with icons

Display nodes with labels and icons to present content in a more readable format. This is helpful in making a typical directory tree and file system.

Check box support

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.

Drag and drop

Inside the tree

Tree nodes can be dragged and dropped from one parent node to another within the same level or different levels.

Outside the tree

Extending the drop behavior allows users to drop tree nodes from one treeview to another treeview.

To an external container

Drop tree nodes to any external container or component by extending the treeview node drop action.

Multiple node selection

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.

Editable nodes

Edit the tree nodes’ label text on the client side by double-clicking it. While editing treeview nodes, the treeview data source will also be updated by the modified data.

Sorting tree nodes

Render the TreeView nodes in ascending or descending order based on the label text to provide users improved readability.

Node template

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 can include images and any custom element structure.

✅ Can I purchase the Syncfusion Angular TreeView component separately?

No, our 65 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 65 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.
