The Dropdown Tree component is a textbox component that allows the user to select single or multiple values from hierarchical data in a tree-like structure. It has several out-of-the-box features, such as data binding, check boxes, templates, UI customization, accessibility, and preselected values.

Data binding

You can bind data to the Dropdown Tree component from a variety of data sources. The data can be local or in any remote service and fetched using different kinds of adapters like OData, OData V4, URL, JSON, and Web API.

Render modes

The Dropdown Tree component has different render modes to visualize selected items.

Box mode

The selected items are displayed as a chip (box) in the Dropdown Tree input box.

Delimiter mode

Default mode

The default mode is a combination of both the box and delimiter modes. When the component is in focus, the selected items will be displayed as chips similar to the box mode. Otherwise, the selected items will be displayed with a delimiter character as in the delimiter mode.

Template mode

Check box support

The Angular Dropdown Tree component provides built-in support for check boxes, allowing users to select more than one item. Enabling the check boxes and auto-check functionality makes the parent and child items dependent on each other. This component also provides a Select All option of all items in the pop-up.

Multiple selection

The Dropdown Tree component allows users to select more than one item in the pop-up through the multi-selection functionality.

Header template

Design your own header for the pop-up tree using the header template.
