Composition

Field

A single control with label, helper text, and validation.

Field
├── FieldLabel
├── Input / Textarea / Switch / Select
├── FieldDescription
└── FieldError

FieldGroup

Related fields in one group. Use FieldSeparator between sections when needed.

FieldGroup
├── Field
│   ├── FieldLabel
│   ├── Input / Textarea / Switch / Select
│   ├── FieldDescription
│   └── FieldError
├── FieldSeparator
└── Field
    ├── FieldLabel
    └── Input / Textarea / Switch / Select

FieldSet

Semantic grouping with a legend and description, usually containing a FieldGroup.

FieldSet
├── FieldLegend
├── FieldDescription
└── FieldGroup
    ├── Field
    │   ├── FieldLabel
    │   ├── Input / Textarea / Switch / Select
    │   ├── FieldDescription
    │   └── FieldError
    └── Field
        ├── FieldLabel
        └── Input / Textarea / Switch / Select

Anatomy

The Field family is designed for composing accessible forms. A typical field is structured as follows:

<Field>
  <FieldLabel htmlFor="input-id">Label</FieldLabel>
  {/* Input, Select, Switch, etc. */}
  <FieldDescription>Optional helper text.</FieldDescription>
  <FieldError>Validation message.</FieldError>
</Field>

• Field is the core wrapper for a single field.
• FieldContent is a flex column that groups label and description. Not required if you have no description.
• Wrap related fields with FieldGroup, and use FieldSet with FieldLegend for semantic grouping.

Form

See the Form documentation for building forms with the Field component and React Hook Form, Tanstack Form, or Formisch.

Input

Textarea

Select

Slider

Fieldset

Checkbox

Radio

Switch

Choice Card

Wrap Field components inside FieldLabel to create selectable field groups. This works with RadioItem, Checkbox and Switch components.

Field Group

Stack Field components with FieldGroup. Add FieldSeparator to divide them.

从右到左布局

To enable RTL support in JGuang UI, see the RTL configuration guide.

Responsive Layout

• Vertical fields: Default orientation stacks label, control, and helper text—ideal for mobile-first layouts.
• Horizontal fields: Set orientation="horizontal" on Field to align the label and control side-by-side. Pair with FieldContent to keep descriptions aligned.
• Responsive fields: Set orientation="responsive" for automatic column layouts inside container-aware parents. Apply @container/field-group classes on FieldGroup to switch orientations at specific breakpoints.

Validation and Errors

• Add data-invalid to Field to switch the entire block into an error state.
• Add aria-invalid on the input itself for assistive technologies.
• Render FieldError immediately after the control or inside FieldContent to keep error messages aligned with the field.

<Field data-invalid>
  <FieldLabel htmlFor="email">Email</FieldLabel>
  <Input id="email" type="email" aria-invalid />
  <FieldError>Enter a valid email address.</FieldError>
</Field>

Accessibility

• FieldSet and FieldLegend keep related controls grouped for keyboard and assistive tech users.
• Field outputs role="group" so nested controls inherit labeling from FieldLabel and FieldLegend when combined.
• Apply FieldSeparator sparingly to ensure screen readers encounter clear section boundaries.

API 参考

FieldSet

Container that renders a semantic fieldset with spacing presets.

Prop	Type	Default
className	string

<FieldSet>
  <FieldLegend>Delivery</FieldLegend>
  <FieldGroup>{/* Fields */}</FieldGroup>
</FieldSet>

FieldLegend

Legend element for a FieldSet. Switch to the label variant to align with label sizing.

Prop	Type	Default
variant	"legend" | "label"	"legend"
className	string

<FieldLegend variant="label">Notification Preferences</FieldLegend>

The FieldLegend has two variants: legend and label. The label variant applies label sizing and alignment. Handy if you have nested FieldSet.

FieldGroup

Layout wrapper that stacks Field components and enables container queries for responsive orientations.

Prop	Type	Default
className	string

<FieldGroup className="@container/field-group flex flex-col gap-6">
  <Field>{/* ... */}</Field>
  <Field>{/* ... */}</Field>
</FieldGroup>

Field

The core wrapper for a single field. Provides orientation control, invalid state styling, and spacing.

Prop	Type	Default
orientation	"vertical" | "horizontal" | "responsive"	"vertical"
className	string
data-invalid	boolean

<Field orientation="horizontal">
  <FieldLabel htmlFor="remember">Remember me</FieldLabel>
  <Switch id="remember" />
</Field>

FieldContent

Flex column that groups control and descriptions when the label sits beside the control. Not required if you have no description.

Prop	Type	Default
className	string

<Field>
  <Checkbox id="notifications" />
  <FieldContent>
    <FieldLabel htmlFor="notifications">Notifications</FieldLabel>
    <FieldDescription>Email, SMS, and push options.</FieldDescription>
  </FieldContent>
</Field>

FieldLabel

Label styled for both direct inputs and nested Field children.

Prop	Type	Default
className	string
asChild	boolean	false

<FieldLabel htmlFor="email">Email</FieldLabel>

FieldTitle

Renders a title with label styling inside FieldContent.

Prop	Type	Default
className	string

<FieldContent>
  <FieldTitle>Enable Touch ID</FieldTitle>
  <FieldDescription>Unlock your device faster.</FieldDescription>
</FieldContent>

FieldDescription

Helper text slot that automatically balances long lines in horizontal layouts.

Prop	Type	Default
className	string

<FieldDescription>We never share your email with anyone.</FieldDescription>

FieldSeparator

Visual divider to separate sections inside a FieldGroup. Accepts optional inline content.

Prop	Type	Default
className	string

<FieldSeparator>Or continue with</FieldSeparator>

FieldError

Accessible error container that accepts children or an errors array (e.g., from react-hook-form).

Prop	Type	Default
errors	Array<{ message?: string } | undefined>
className	string

<FieldError errors={errors.username} />

When the errors array contains multiple messages, the component renders a list automatically.

FieldError also accepts issues produced by any validator that implements Standard Schema, including Zod, Valibot, and ArkType. Pass the issues array from the schema result directly to render a unified error list across libraries.
