Select

react-hook-form-bound single-value dropdown. Wraps the @uxf/ui/select primitive and manages its value, isInvalid, and helperText from form state.

When to use

Use @uxf/form/select for a single-choice picker 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 select (outside a form), use the @uxf/ui/select twin directly.

• Need to filter options by typing? Use @uxf/form/combobox.
• Need to pick several values? Use @uxf/form/multi-select.

Usage

import { Form } from "@uxf/form/form";
import { Select, SelectValue } from "@uxf/form/select";
import { useForm } from "react-hook-form";

interface FormData {
    country: SelectValue<string>;
}

const options = [
    { id: "cz", label: "Czechia" },
    { id: "sk", label: "Slovakia" },
];

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

    return (
        <Form formApi={formApi} id="example" onSubmit={(values) => console.log(values)}>
            <Select
                control={formApi.control}
                isRequired
                label="Country"
                name="country"
                options={options}
                placeholder="Select..."
            />
        </Form>
    );
}

The react-hook-form value is the selected option's id (string | number) or null — the same shape as the @uxf/ui/select twin (SelectValue<T> = T | null). It is read from and written to the twin unchanged (no normalisation).

Props

SelectProps<FormData> = ControlProps<FormData> + the visual props of the @uxf/ui/select twin (minus the ones this field manages: inputGroupRef, inputRef, inputWrapperRef, isFocused, isInvalid, name, onChange, value) + the field-specific props below.

All visual props (label, options, placeholder, isClearable, size, variant, helperText, renderOption, renderSelectedOption, keyExtractor, iconName, leftAddon/rightAddon/leftElement/rightElement, the dropdown* props, …) are forwarded to the twin — see @uxf/ui/select.

Validation

• isRequired adds a required rule; override its message with requiredMessage (default localized "This field is required", key uxf-form-select:validation.required).
• Add any further rules via rules; they are merged with the built-in rule.
• 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 for the default id = ${formId}__${name}, and inherits isDisabled / isReadOnly) and needs a react-hook-form control.
• The control is auto-disabled when options is empty (in addition to the form's isDisabled and the field's own isDisabled).
• Ships no CSS of its own; it renders @uxf/ui/select, so include that component's stylesheet(s) and the @uxf/ui token layer — see @uxf/ui/select.
