@aphrody/m3-forms

Material Design 3 form fields for React, wired to react-hook-form. Each field composes a control from @aphrody/m3-primitives with the M3 text-field anatomy: a label, the control, then supporting text (or error text) 4dp below it.

This is SpaceUI's @spacedrive/forms rebuilt on Material Design 3. The upstream source lives in packages/aphrody-spaceui/packages/forms; the fusion rules are in docs/design/SPACEUI-M3-FUSION.md.

Install

bun add @aphrody/m3-forms @aphrody/m3-primitives react-hook-form zod @hookform/resolvers

Peer dependencies: react and react-dom 18 or 19, react-hook-form 7, zod (3 or 4), tailwindcss 4.1+.

CSS setup

The components use the M3 Tailwind utilities (text-body-small, text-error, bg-surface-container-highest, …). Import the token sheets and let Tailwind scan the package, as described in SPACEUI-M3-FUSION.md → Integration:

@import "tailwindcss";
@import "@aphrody/m3-tokens/m3-tokens.css";
@import "@aphrody/m3-theme/spaceui.css"; /* or tokens.css */
@import "@aphrody/m3-theme/tailwind.css";

@source "../node_modules/@aphrody/m3-primitives/dist";
@source "../node_modules/@aphrody/m3-forms/dist";

Error messages carry a Material Symbols error glyph: register the font once with ensureMaterialSymbols() from @aphrody/material-web/icon/material-symbols.js.

Example (zod 4 + react-hook-form)

import { zodResolver } from "@hookform/resolvers/zod";
import { useForm } from "react-hook-form";
import { z } from "zod";
import { Button } from "@aphrody/m3-primitives";
import {
  CheckboxField,
  Form,
  InputField,
  RadioGroupField,
  SelectField,
  SwitchField,
  TextAreaField,
} from "@aphrody/m3-forms";

const schema = z.object({
  name: z.string().min(2, "At least 2 characters"),
  email: z.email("Enter a valid email"),
  role: z.enum(["admin", "user"]),
  bio: z.string().max(280).optional(),
  plan: z.enum(["free", "pro"]),
  notifications: z.boolean(),
  terms: z.literal(true, { error: "You must accept the terms" }),
});

type Values = z.infer<typeof schema>;

export function ProfileForm() {
  const form = useForm<Values>({
    resolver: zodResolver(schema),
    defaultValues: { name: "", email: "", role: "user", plan: "free", notifications: true },
  });

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(console.log)} className="flex flex-col gap-6">
        <InputField name="name" label="Full name" required />
        <InputField
          name="email"
          label="Email"
          type="email"
          description="Used for sign-in"
          required
        />
        <SelectField
          name="role"
          label="Role"
          options={[
            { value: "admin", label: "Administrator" },
            { value: "user", label: "User" },
          ]}
        />
        <TextAreaField name="bio" label="Bio" rows={3} />
        <RadioGroupField
          name="plan"
          label="Plan"
          options={[
            { value: "free", label: "Free" },
            { value: "pro", label: "Pro" },
          ]}
        />
        <SwitchField
          name="notifications"
          label="Notifications"
          description="Push alerts on this device"
        />
        <CheckboxField name="terms" label="I accept the terms" required />
        <Button type="submit" variant="filled">
          Save
        </Button>
      </form>
    </Form>
  );
}

Components

Export	Role
Form	react-hook-form's FormProvider.
FormField	Controller plus the field-name context.
FormItem	One field: a column with 4dp gaps. Set data-disabled to dim label and supporting text to 38 %.
FormLabel	text-label-large above a text field (variant="field", error-colored when invalid) or text-body-large beside a checkbox, radio or switch (variant="inline"). required appends *.
FormControl	Wires id, aria-invalid and aria-describedby (description, then message) onto its child.
FormDescription	M3 supporting text: text-body-small text-on-surface-variant.
FormMessage	M3 error text: text-body-small text-error with a leading 16px error icon. Renders the field error, or its children.
useFormField	Ids and field state of the enclosing field.
InputField, TextAreaField, SelectField	Text-field family: the control shows the error outline (border-error); supporting text is inset 16px to line up with the input text.
CheckboxField, RadioGroupField, SwitchField	Selection controls with inline labels; supporting and error text sit under the label.

Every field takes name, label, description, disabled and required; InputField adds placeholder and type, TextAreaField adds placeholder and rows, SelectField adds placeholder and options, RadioGroupField adds options.

Differences from @spacedrive/forms

• M3 anatomy and roles: supporting text in on-surface-variant, error text in error with an icon, label in error when the field is invalid, disabled at 38 %.
• required on every field (* marker, required / aria-required on the control).
• TextAreaField composes the TextArea primitive instead of a raw <textarea>.
• Field props types (InputFieldProps, …) and FormLabelProps are exported.
