Live TypeScript example
Try the component here, then use the source below in your application.
Open the selector and choose an item.
import '@bluui/web/styles.css'
import { createTreeSelect } from "@bluui/web";
export function mount(host: HTMLElement) {
return createTreeSelect(
host,
{
IsMultiple: true,
LeavesOnly: true,
AccessibleLabel: "Teams",
Nodes: [
{ Key: "company", Label: "Company" },
{ Key: "design", ParentKey: "company", Label: "Design" },
{ Key: "engineering", ParentKey: "company", Label: "Engineering" },
],
},
{
SelectionChanged: (keys) => {
host.dataset.selected = keys.join(",");
},
},
);
}
const instance = mount(document.getElementById('example')!)
// When this page or framework component is removed:
// instance.destroy()
Install the library and add the host element

Evidence and remaining verification →Purpose and use
Use TreeSelect for hierarchical choices in a compact field. Allow multiple selection when more than one leaf can be assigned.
Keyboard design guidance
Open the field with Enter or Space. Use the search field to narrow choices. Navigate available controls with Tab and close the popup with Escape.
This describes the intended interaction. The dated audit above identifies verified behavior and current gaps.
In your application
Provide useful labels, preserve visible focus, and test the component with your actual content. Use text alongside status colors and check contrast in each state.
