Usage

When to use

Use it inside forms, filters, settings, and any workflow that captures user input.
Prefer controlled props when the value must stay synchronized with application state.

Implementation notes

Stylesheet Import @duskmoon-dev/components/styles.css once in the app or docs shell.

State Start with default props for static examples, then switch to controlled props when state must be shared.

Theme The preview inherits the active DuskMoon data-theme value from the docs layout.

Features

Controlled and uncontrolled usage

Documents default values, value props, and change callbacks for form integration.

Validation state

Surfaces status, size, disabled, and option data patterns where the component supports them.

Primary API surface

TreeSelect is most often configured through `allowClear`, `defaultOpen`, `defaultValue`, `defaultExpandedKeys`.

Covered behavior

Renders treeData and selects a single value
