# Form

A high-quality, unstyled Solid form component with consolidated error handling.

## Demo

### Tailwind

This example shows how to implement the component using Tailwind CSS.

```tsx
/* index.tsx */
import { createSignal } from 'solid-js';
import { Field } from 'base-ui-solid/field';
import { Form } from 'base-ui-solid/form';
import { Button } from 'base-ui-solid/button';

export default function ExampleForm() {
  const [errors, setErrors] = createSignal({});
  const [loading, setLoading] = createSignal(false);

  return (
    <Form
      class="flex w-full max-w-64 flex-col gap-4"
      errors={errors()}
      onSubmit={async (event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        const value = formData.get('url') as string;

        setLoading(true);
        const response = await submitForm(value);
        const serverErrors = {
          url: response.error,
        };

import { createSignal } from 'solid-js';
import { Field } from 'base-ui-solid/field';
import { Form } from 'base-ui-solid/form';
import { Button } from 'base-ui-solid/button';
import styles from './index.module.css';

export default function ExampleForm() {
  const [errors, setErrors] = createSignal({});
  const [loading, setLoading] = createSignal(false);

  return (

  await new Promise((resolve) => {

    if (url.hostname.endsWith('example.com')) {
      return { error: 'The example domain is not allowed' };
    }
  } catch {
    return { error: 'This is not a valid URL' };
  }

  return { success: true };
}
```

## Anatomy

Form is composed together with [Field](/solid/components/field.md). Import the components and place them together:

```jsx title="Anatomy"
import { Field } from 'base-ui-solid/field';
import { Form } from 'base-ui-solid/form';

<Form>
  <Field.Root>
    <Field.Label />
    <Field.Control />
    <Field.Error />
  </Field.Root>
</Form>;
```

## Examples

### Submit with a Server Function

Use a native `onSubmit` handler to collect `FormData`, call your server function, and update the returned field errors and loading state with Solid signals.

### Submit form values as a JavaScript object

You can use `onFormSubmit` instead of the native `onSubmit` to access form values as a JavaScript object. This is useful when you need to transform the values before submission, or integrate with 3rd party APIs.

```tsx title="Submission using onFormSubmit"
<Form
  onFormSubmit={async (formValues: { id: string; quantity: number }) => {
    const payload = {
      product_id: formValues.id,
      order_quantity: formValues.quantity,
    };

    const response = await fetch('https://api.example.com', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(payload),
    });
  }}
/>
```

When used, `preventDefault` is called on the native submit event.

### Using with Zod

When parsing the schema using `schema.safeParse()`, the `z.flattenError(result.error).fieldErrors` data can be used to map the errors to each field's `name`.

## Demo

### Tailwind

This example shows how to implement the component using Tailwind CSS.

```tsx
/* index.tsx */
import { createSignal } from 'solid-js';
import { z } from 'zod';
import { Field } from 'base-ui-solid/field';
import { Form } from 'base-ui-solid/form';
import { Button } from 'base-ui-solid/button';

const schema = z.object({
  name: z.string().min(1, 'Name is required'),
  age: z.coerce.number('Age must be a number').positive('Age must be a positive number'),
});

async function submitForm(formValues: Form.Values) {
  const result = schema.safeParse(formValues);

  if (!result.success) {
    return {
      errors: z.flattenError(result.error).fieldErrors,
    };
  }

  return {
    errors: {},
  };
}

export default function Page() {
  const [errors, setErrors] = createSignal({});

  return (
    <Form
      class="flex w-full max-w-64 flex-col gap-4"
