DevExtreme Accessibility Compliance
DevExtreme component libraries meet a variety of WCAG and Section 508 compliance standards. To assess this demo’s accessibility level, click the Run AXE® Validation button to launch the AXE® web accessibility evaluation tool.
All trademarks or registered trademarks are property of their respective owners. AXE® Terms of Use
The overall accessibility level of your application depends on the TreeView features used.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
Backend API

Each object in the TreeView's hierarchical data structure should include the following fields:

  • id
    Unique item identifier.

  • text
    Text displayed by the item.

  • items
    Nested objects (optional).

You can respectively use the keyExpr, displayExpr, and itemsExpr properties to specify custom names for the above-mentioned fields. Node objects can also include developer-defined fields and properties from this help section: items[].

In this demo, nodes use the expanded property, which specifies whether a node is collapsed or expanded. They also include the developer-defined price and image fields.
