# Accordion

Host: Radix UI. Path: keyframes. Preset: `collapse`. Built against [radix-ui 1.6.7](https://www.npmjs.com/package/radix-ui/v/1.6.7).

Identical state contract to Collapsible, and the preset is the same one. The panel takes a single element child, which is the part that gets clipped.

The page this file mirrors mounts the component twice, once with the attribute and once without, so the only difference between the two is the library.

Upstream documentation: [Radix UI documentation](https://www.radix-ui.com/primitives/docs/components/accordion)

The same component in other hosts: [Base UI](/base-ui/accordion.md).

## Where the attribute goes

The parts this demo composes, and the value each one carries. Everything inside an animated part is that part's content, so the tree stops there.

```text
Accordion.Root
  Accordion.Item
    Accordion.Header
      Accordion.Trigger
    Accordion.Content  data-motion="collapse"
```

## How the match works

| Step | Value |
| --- | --- |
| host writes | `data-state="open" \| "closed"` |
| easeful matches | `[data-motion~="collapse"][data-state="closed"]` |
| what runs | `animation: motion-exit, motion-collapse-exit` |
| you write | `<Accordion.Content data-motion="collapse" />` |

## Every value that works here

Every value the manifest allows on this host, single presets and the pairs that compose. The first is what this component ships with. Both stages are the same component, so anything that changes between them is the attribute.

| Value | Link |
| --- | --- |
| `collapse` | the default |
| `fade` | [fade](/radix/accordion#motion=fade) |
| `scale-fade` | [scale-fade](/radix/accordion#motion=scale-fade) |
| `slide-up` | [slide-up](/radix/accordion#motion=slide-up) |
| `fade collapse` | [fade collapse](/radix/accordion#motion=fade%20collapse) |
| `fade slide-up` | [fade slide-up](/radix/accordion#motion=fade%20slide-up) |
| `scale-fade slide-up` | [scale-fade slide-up](/radix/accordion#motion=scale-fade%20slide-up) |

```tsx
"use client"

import { Accordion } from "radix-ui"
import type { DemoProps } from "@/components/demos/props"

export function RadixAccordion({ motion }: DemoProps) {
  return (
    <Accordion.Root type="single" collapsible>
      <Accordion.Item value="one">
        <Accordion.Header style={{ margin: 0 }}>
          <Accordion.Trigger className="btn">What ships to the browser?</Accordion.Trigger>
        </Accordion.Header>
        <Accordion.Content data-motion={motion}>
          <div className="panel" style={{ marginTop: 12 }}>
            <p className="panel__body">
              CSS only. A grid row carries the collapse, so one preset covers both components and
              neither reads a height variable.
            </p>
          </div>
        </Accordion.Content>
      </Accordion.Item>
    </Accordion.Root>
  )
}
