Usage

Field wraps any input control with a label, description, and validation status. Use it to build accessible forms with consistent labeling, optional/required indicators, and inline error, warning, or success feedback.

Best practices

Guidance	Practices
Do	Always provide a label for accessibility, even if visually hidden with isLabelHidden.
Do	Use the status prop with clear messages to provide inline validation feedback.
Do	Add a description when the label alone does not explain what the field expects, like format hints or constraints.
Don't	Set both isOptional and isRequired on the same field.
Don't	Use the detached status variant on bordered inputs — reserve it for checkboxes, switches, and sliders.
Don't	Hide the label without providing an alternative way for the user to understand the field purpose.

Anatomy

Element		Description
Label	required	Text identifying the field. Always rendered for accessibility, optionally hidden visually.
Description		Helper text between the label and input explaining what to enter.
Input slot	required	The input control wrapped by the field — TextInput, Select, DateInput, etc.
Status message		Inline validation feedback showing error, warning, or success with a message.
Optional/Required indicator		Badge next to the label showing whether the field is optional or required.
Label tooltip		Info icon at the end of the label with a tooltip explaining the field.

Import

ts
import {XDSField} from '@xds/core/Field'

Props

Prop	Type	Description
labelrequired	string	Label text for the field (always rendered for accessibility).
inputIDrequired	string	ID for the input element (used for the label htmlFor attribute).
childrenrequired	ReactNode	The input or control to render.
isLabelHidden	boolean (default: false)	Visually hide the label (still accessible to screen readers).
isDisabled	boolean (default: false)	Whether the associated input is disabled. Propagates disabled styling to the label.
description	string	Description text displayed between the label and input.
descriptionID	string	ID for the description element (use for aria-describedby on the input).
isOptional	boolean (default: false)	Whether the field is optional (mutually exclusive with isRequired).
isRequired	boolean (default: false)	Whether the field is required (mutually exclusive with isOptional).
labelIcon	XDSIconType	Icon to display before the label text. See `npx xds docs icons` for valid semantic names.
labelTooltip	string	Tooltip text to display in an info icon at the end of the label.
status	XDSFieldStatus	Status indicator with type and optional message. When message is set, displays a colored status box.
statusVariant	'attached' \| 'detached' (default: 'attached')	How the status message renders relative to the input. Attached overlaps the input border; detached floats below.
ref	React.Ref<HTMLDivElement>	Ref forwarded to the root element.
xstyle	StyleXStyles	StyleX styles for layout customization (margins, positioning, sizing). Must be a stylex.create() value — not an inline style object like style={{}}.
className	string	CSS class name(s) appended to the root element. Prefer xstyle for StyleX deduplication.
style	React.CSSProperties	Inline styles applied to the root element. Takes priority over StyleX inline styles.

Examples

Common configurations, variations, and states.

Field — DescriptionFields with helper text below the label. Use descriptions to explain format requirements, constraints, or what happens with the data — like

tsx
'use client';
import {useState} from 'react';
import {XDSTextInput} from '@xds/core/TextInput';
import {XDSVStack} from '@xds/core/Layout';
import {XDSCenter} from '@xds/core/Center';
export default function FieldWithDescription() {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  return (
    <XDSCenter>
      <XDSVStack gap={4}>
        <XDSTextInput
          label="Email"
          description="We'll send a confirmation link to this address"
          value={email}
          onChange={setEmail}
          placeholder="you@example.com"
        />
        <XDSTextInput
          label="Password"
          description="At least 8 characters with one uppercase letter"
          value={password}
          onChange={setPassword}
          placeholder="Create a password"
        />
      </XDSVStack>
    </XDSCenter>
  );
}

Field — Required & OptionalRequired and optional field indicators side by side. Use isRequired on fields the user must fill in, and isOptional to clarify which fields can be skipped.

tsx
'use client';
import {useState} from 'react';
import {XDSTextInput} from '@xds/core/TextInput';
import {XDSVStack} from '@xds/core/Layout';
import {XDSCenter} from '@xds/core/Center';
export default function FieldRequired() {
  const [username, setUsername] = useState('');
  const [email, setEmail] = useState('');
  return (
    <XDSCenter>
      <XDSVStack gap={4}>
        <XDSTextInput
          label="Username"
          isRequired
          value={username}
          onChange={setUsername}
          placeholder="Enter your username"
        />
        <XDSTextInput
          label="Backup email"
          isOptional
          value={email}
          onChange={setEmail}
          placeholder="you@example.com"
        />
      </XDSVStack>
    </XDSCenter>
  );
}

Field — Validation StatesAll three validation states: error, warning, and success. Use error for invalid input, warning for potential issues like reserved names, and success to confirm valid entries like API keys.

tsx
'use client';
import {useState} from 'react';
import {XDSTextInput} from '@xds/core/TextInput';
import {XDSVStack} from '@xds/core/Layout';
import {XDSCenter} from '@xds/core/Center';
export default function FieldStatusVariants() {
  const [email, setEmail] = useState('bad-email');
  const [username, setUsername] = useState('admin');
  const [apiKey, setApiKey] = useState('sk-live-abc123');
  return (
    <XDSCenter>
      <XDSVStack gap={4}>
        <XDSTextInput
          label="Email"
          description="Enter your work email"
          value={email}
          onChange={setEmail}
          status={{
            type: 'error',
            message: 'Please enter a valid email address',
          }}
        />
        <XDSTextInput
          label="Username"
          description="Choose a unique username"
          value={username}
          onChange={setUsername}
          status={{
            type: 'warning',
            message: 'This username is reserved for administrators',
          }}
        />
        <XDSTextInput
          label="API Key"
          description="Paste your API key"
          value={apiKey}
          onChange={setApiKey}
          status={{type: 'success', message: 'API key is valid and active'}}
        />
      </XDSVStack>
    </XDSCenter>
  );
}

export default function FieldShowcase() {
  const [email, setEmail] = useState('');
  const status =
    email.length > 0 && !email.includes('@')
      ? {type: 'error' as const, message: 'Enter a valid email address.'}
      : undefined;
  return (
    <XDSStack direction="vertical" gap={3} xstyle={styles.root}>
      <XDSField
        label="Email"
        inputID="field-email"
        description="We will never share your email."
        isRequired
        status={status}>
        <XDSTextInput
          label="Email"
          isLabelHidden
          value={email}
