# Switch

Mit einem Switch können User Optionen ein- oder ausschalten. Die Component wird normalerweise verwendet, um bestimmte Einstellungen zu aktivieren oder zu deaktivieren.

## Overview

# Playground

Verwende `<Switch />`, um einen Switch darzustellen.

```tsx
import { Switch } from "@mittwald/flow-react-components";

<Switch defaultSelected>Autoresponder</Switch>
```

---

# Label-Position: Links

Die Positionierung des Labels sollte sich am Seitenlayout orientieren. Steht der Switch rechtsbündig, sollte die Beschriftung links davor platziert werden.
So erfasst der User zuerst den Zweck, bevor die Aktion ausführt wird.

```tsx
import { Switch } from "@mittwald/flow-react-components";

<Switch labelPosition="leading">Autoresponder</Switch>
```

---

# Disabled

In Ausnahmefällen kann ein deaktivierter Switch verwendet werden, um eine Funktion temporär als nicht verfügbar darzustellen, ohne diesen vollständig aus der Oberfläche zu entfernen.

```tsx
import { Switch } from "@mittwald/flow-react-components";

<Switch isDisabled>Autoresponder</Switch>
```

# Properties

| Property | Type | Default | Description |
| --- | --- | --- | --- |
| `labelPosition` | `"leading" \| "trailing"` | `"trailing"` | Whether the label should appear before or after the switch. |
| `id` | `string` | - | The element's unique identifier. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id). |
| `translate` | `"yes" \| "no"` | - | - |
| `className` | `ClassNameOrFunction<SwitchRenderProps>` | `'react-aria-Switch'` | The CSS [className](https://developer.mozilla.org/en-US/docs/Web/API/Element/className) for the element. A function may be provided to compute the class based on component state. |
| `style` | `StyleOrFunction<TooltipRenderProps>` | - | The inline [style](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/style) for the element. A function may be provided to compute the style based on component state. |
| `render` | `DOMRenderFunction<"div", TooltipRenderProps>` | - | Overrides the default DOM element with a custom render function. This allows rendering existing components with built-in styles and behaviors such as router links, animation libraries, and pre-styled components. Requirements: - You must render the expected element type (e.g. if `<button>` is expected, you cannot render an `<a>`). - Only a single root DOM element can be rendered (no fragments). - You must pass through props and ref to the underlying DOM element, merging with your own prop as appropriate. |
| `dir` | `string` | - | - |
| `lang` | `string` | - | - |
| `hidden` | `boolean` | - | - |
| `inert` | `boolean` | - | - |
| `isDisabled` | `boolean` | - | Whether the input is disabled. |
| `isReadOnly` | `boolean` | - | Whether the input can be selected but not changed by the user. |
| `autoFocus` | `boolean` | - | Whether the element should receive focus on render. |
| `value` | `string` | - | The value of the input element, used when submitting an HTML form. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefvalue). |
| `name` | `string` | - | The name of the input element, used when submitting an HTML form. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefname). |
| `form` | `string` | - | The `<form>` element to associate the input with. The value of this attribute must be the id of a `<form>` in the same document. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input#form). |
| `slot` | `string` | - | A slot name for the component. Slots allow the component to receive props from a parent component. An explicit `null` value indicates that the local props completely override all props received from a parent. |
| `excludeFromTabOrder` | `boolean` | - | Whether to exclude the element from the sequential tab order. If true, the element will not be focusable via the keyboard by tabbing. This should be avoided except in rare scenarios where an alternative means of accessing the element or its functionality via the keyboard is available. |
| `defaultSelected` | `boolean` | - | Whether the element should be selected (uncontrolled). |
| `isSelected` | `boolean` | - | Whether the element should be selected (controlled). |
| `children` | `ReactNode` | - | - |
| `wrapWith` | `ReactElement<unknown, string \| JSXElementConstructor<any>>` | - | - |
| `ref` | `Ref<HTMLSpanElement>` | - | Allows getting a ref to the component instance. Once the component unmounts, React will set `ref.current` to `null` (or call the ref with `null` if you passed a callback ref). @see [React Docs](https://react.dev/learn/referencing-values-with-refs#refs-and-the-dom) |
| `key` | `Key` | - | - |

## Guidelines

# Grundlagen

Ein Switch ermöglicht das unmittelbare Aktivieren oder Deaktivieren einer
Option. Die Änderungen treten sofort in Kraft, ohne dass eine separate
Bestätigung notwendig ist.

## Best practices

Achte bei der Verwendung von einem Switch darauf, dass ...

- Änderungen sofort übernommen werden, ohne dass ein zusätzlicher
  Speichern-Button nötig ist.
- das Label die Funktion klar und prägnant beschreibt (idealerweise in 1–3
  Wörtern).
- die Beschriftung unabhängig vom Zustand des Switches gleich bleibt.

## Verwendung

Verwende einen Switch, um ...

- den aktuellen Status einer Einstellung jederzeit sichtbar zu machen.
- Optionen direkt zu aktivieren oder zu deaktivieren – ohne zusätzlichen
  Bestätigungsschritt.
- häufig genutzte Optionen schnell und unkompliziert ändern zu können.
