# Accordion

```gistui
root = Accordion(Item("What is GistUI?", "A rendering engine for generative UI.", open), Item("Is it open source?", "Yes, under the MIT licence."), Item("Which frameworks?", "React, Vue, Svelte, Solid and vanilla JavaScript."))
```

## Signature

This is the line a model reads in the system prompt.

```gistui
Accordion(...Item, multiple)
```

- **Group:** Layout
- **Children:** Yes: Item
- **Positional arguments:** none

## Props

| Prop | Type | How to write it | Notes |
|---|---|---|---|
| `multiple` | flag | bare word: `multiple` |  |

## Use your own component

Keep the name and schema, swap what is drawn. The prompt and the model's output do not change.

import { ui } from "@gistui/react/ui";

const lib = ui.extend({ Accordion: MyAccordion });
<GistUI library={lib} stream={response.body} />;
