TextArea

Die TextArea ermöglicht es dem User, längere Texte über mehrere Zeilen hinweg einzugeben.

Public Key(optional)Beginnt mit ssh-rsa

import {
  FieldDescription,
  Label,
  TextArea,
} from "@mittwald/flow-react-components";

<TextArea>
  <Label>Public Key</Label>
  <FieldDescription>Beginnt mit ssh-rsa</FieldDescription>
</TextArea>

Best Practices

Wähle die Höhe über das Property rows passend zur erwarteten Textmenge.
Formuliere das Label‍ prägnant und leicht verständlich.
Nutze die FieldDescription für Beispiele, Formatierungshinweise oder Kontext.
Formuliere Fehlermeldungen‍ klar, hilfreich und lösungsorientiert.

Character Count

Mit der Property showCharacterCount wird automatisch eine <FieldDescription /> ergänzt, die die aktuelle Zeichenanzahl und – sofern angegeben – die maximale Zeichenanzahl anzeigt.

Nachricht(optional)0/100 characters

Validierung

Nutze für die Validierung React Hook Form‍. Alternativ stehen aber auch folgende Properties zur Verfügung:

isRequired für Pflichtfelder.
validate für eigene Validierungen.
HTML Input Properties wie minLength.

Bei ungültiger Eingabe wird die TextArea invalidiert. Über <FieldError /> kann eine entsprechende Fehlermeldung ausgegeben werden.

Required

Public Key

Invalid

Public Key(optional)Ungültiger Key

Resize

Automatisch

Mit der Property autoResizeMaxRows lässt sich eine maximale Höhe definieren, bis zu der sich die TextArea automatisch an den Inhalt anpasst.

Nachricht(optional)

Manuell

Über die Properties allowResize, allowVerticalResize oder allowHorizontalResize kann die Größe der TextArea manuell verändert werden.

Nachricht(optional)

Kombiniert

Beide Resize-Varianten lassen sich auch miteinander kombinieren. In diesem Fall passt sich die TextArea zunächst automatisch an, bis die Größe einmal manuell geändert wird. Danach bleibt sie in der eingestellten Größe bestehen.

Nachricht(optional)

Disabled

Achte bei der Verwendung von Disabled darauf, dass aus dem Kontext klar wird, warum der User gerade nicht mit der TextArea interagieren kann.

Public Key(optional)

Kombiniere mit ...

Combine

Benutze die Combine‍-Component, um andere Components, wie einen Button‍, neben der TextArea auszurichten.

Nachricht(optional)

ContextualHelp

Verwende ContextualHelp‍, um zusätzliche Informationen bereitzustellen, die über den Umfang der FieldDescription hinausgehen.

Property	Type	Description
`allowHorizontalResize`	boolean	@deprecated Use `allowResize` instead.
`allowResize`	boolean \| horizontal \| vertical	Allows the user to manually resize the textArea horizontally.
`allowVerticalResize`	boolean	@deprecated Use `allowResize` instead.
`autoComplete`	string	Describes the type of autocomplete functionality the input should provide if any. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefautocomplete).
`autoCorrect`	string	An attribute that takes as its value a space-separated string that describes what, if any, type of autocomplete functionality the input should provide. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#autocomplete).
`autoFocus`	boolean	Whether the element should receive focus on render.
`autoResizeMaxRows`	number	Whether the text area should grow if its content gets longer than its initial height.
`children`	ReactNode
`className`	ClassNameOrFunction<TextFieldRenderProps>default: 'react-aria-TextField'	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.
`defaultValue`	TimeValue	The default value (uncontrolled).
`dir`	string
`enterKeyHint`	enter \| done \| go \| next \| previous \| search \| send	An enumerated attribute that defines what action label or icon to preset for the enter key on virtual keyboards. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/enterkeyhint).
`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.
`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).
`hidden`	boolean
`id`	string	The element's unique identifier. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id).
`inert`	boolean
`inputMode`	text \| none \| search \| url \| tel \| email \| numeric \| decimal	Hints at the type of data that might be entered by the user while editing the element or its contents. See [MDN](https://html.spec.whatwg.org/multipage/interaction.html#input-modalities:-the-inputmode-attribute).

`isRequired`	boolean	Whether user input is required on the input before form submission.
`lang`	string
`maxLength`	number	The maximum number of characters supported by the input. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefmaxlength).
`minLength`	number	The minimum number of characters required by the input. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefminlength).
`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).
`pattern`	string	Regex pattern that the value of the input must match to be valid. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefpattern).
`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.
`showCharacterCount`	boolean	Whether a character count should be displayed inside the field description.
`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.
`spellCheck`	string	An enumerated attribute that defines whether the element may be checked for spelling errors. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/spellcheck).
`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.
`translate`	yes \| no
`type`	text (default) \| search \| url \| tel \| email \| password \| (string & {})	The type of input to render. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdeftype).
`validate`	((value: TimeValue) => true \| ValidationError \| null)	A function that returns an error message if a given value is invalid. Validation errors are displayed to the user when the form is submitted if `validationBehavior="native"`. For realtime validation, use the `isInvalid` prop instead.
`validationBehavior`	native (default) \| aria	Whether to use native HTML form validation to prevent form submission when the value is missing or invalid, or mark the field as required or invalid via ARIA.
`value`	TimeValue	The current value (controlled).
`wrapWith`	ReactElement<unknown, string \| JSXElementConstructor<any>>	A React element the component is wrapped with. The element is cloned and receives the component as its only child — useful to render the component inside a link, a tooltip trigger or any other wrapper without changing the surrounding markup.
