Textarea

react-hook-form-bound multiline text field. Wraps the @uxf/ui/textarea primitive and manages its value, isInvalid, and helperText from form state.

When to use

Use @uxf/form/textarea for a multiline text field inside a @uxf/form form — it registers the field with react-hook-form via control/name and renders validation errors automatically. For a standalone, manually-controlled textarea (outside a form), use the @uxf/ui/textarea twin directly.

Usage

import { Form } from "@uxf/form/form";
import { Textarea } from "@uxf/form/textarea";
import { useForm } from "react-hook-form";

interface FormData {
    note: string;
}

function Example() {
    const formApi = useForm<FormData>({ defaultValues: { note: "" } });

    return (
        <Form formApi={formApi} id="example" onSubmit={(values) => console.log(values)}>
            <Textarea control={formApi.control} isRequired label="Note" name="note" placeholder="Enter a note" />
        </Form>
    );
}

Value is string | null (TextareaValue), rendered as an empty string when null.

Props

TextareaProps<FormData> = ControlProps<FormData> + the visual props of the @uxf/ui/textarea twin (minus the ones this field manages: isFocused, isInvalid, name, onChange, value) + the props below.

All other props (label, placeholder, rows, maxLength, minLength, disableAutoHeight, helperText, hiddenLabel, autoComplete, …) are forwarded to the twin — see @uxf/ui/textarea.

Validation

• isRequired adds a required rule; override its message with requiredMessage (default localized via key uxf-form-textarea:validation.required).
• Add any further rules via rules; the field-level error is shown as the twin's helperText and sets isInvalid.

Requirements

• Must be rendered inside a Form — it reads the form context (formId, and inherits isDisabled / isReadOnly) and needs a react-hook-form control.
• Ships no CSS of its own; it renders @uxf/ui/textarea, so include that component's stylesheet(s) and the @uxf/ui token layer — see @uxf/ui/textarea.
