Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/combobox-virtualized-demo.json

Usage

usage.tsx
import ComboboxVirtualizedDemo from "@/examples/combobox-virtualized-demo";export default function Page() {  return <ComboboxVirtualizedDemo />;}
  • Use for large option collections where rendering every option would hurt performance.
  • Use when users need searchable selection from thousands of generated or remote-like records.
  • Use when the results panel should remain compact while supporting keyboard selection and scrolling.
  • Use as a reference for integrating manual filtering with TanStack Virtual.

Examples

Render the standalone virtualized trick picker

Place the demo directly in a page or settings form.

render-the-standalone-virtualized-trick-picker.tsx
import ComboboxVirtualizedDemo from "@/examples/combobox-virtualized-demo";export default function TricksPage() {  return <ComboboxVirtualizedDemo />;}

Use it inside a centered panel

Embed the picker in a constrained layout while preserving its internal virtualized scrolling.

use-it-inside-a-centered-panel.tsx
import ComboboxVirtualizedDemo from "@/examples/combobox-virtualized-demo";export default function TrickSelectorPanel() {  return (    <section className="max-w-sm space-y-4">      <h2 className="text-lg font-semibold">Choose a trick</h2>      <ComboboxVirtualizedDemo />    </section>  );}

Accessibility

  • The visible “Trick” label is rendered through ComboboxLabel and should identify the search control.
  • The search input exposes the placeholder “Search tricks...” and supports filtering as the user types.
  • The underlying Combobox primitives provide combobox option interaction, including selection and keyboard navigation.
  • The dropdown trigger includes an icon-only control; the ComboboxTrigger primitive is responsible for its accessible trigger semantics.
  • Only virtualized rows are mounted at a time, so assistive technology can traverse the currently rendered result set rather than all 10,000 generated options.
  • The empty state announces “No tricks found.” when filtering produces no matching options.
