  );
}

```

### In Surface

When used inside a [Surface](/docs/components/surface) component, use `variant="secondary"` on form controls (Input, TextArea, etc.) to apply the lower emphasis variant suitable for surface backgrounds.

```tsx
"use client";

import {
  Button,
  Description,
  FieldError,
  Fieldset,
  Form,
  Input,
  Label,
  Surface,
  TextArea,
  TextField,
} from "@blakeui/react";
import {FloppyDisk} from "@gravity-ui/icons";
import React from "react";

export function OnSurface() {
  const onSubmit = (e: React.FormEvent<HTMLFormElement>) => {
    e.preventDefault();
    const formData = new FormData(e.currentTarget);
    const data: Record<string, string> = {};

// Convert FormData to plain object
    formData.forEach((value, key) => {
      data[key] = value.toString();
    });

alert("Form submitted successfully!");
  };

return (
    <div className="flex items-center justify-center rounded-3xl bg-surface p-6">
      <Surface className="w-full min-w-[380px]">
        <Form onSubmit={onSubmit}>
          <Fieldset className="w-full">
            <Fieldset.Legend>Profile Settings</Fieldset.Legend>
            <Description>Update your profile information.</Description>
            <Fieldset.Group>
              <TextField
                isRequired
                name="name"
                validate={(value) => {
                  if (value.length < 3) {
                    return "Name must be at least 3 characters";
                  }

return null;
                }}
              >
                <Label>Name</Label>
                <Input placeholder="John Doe" variant="secondary" />
                <FieldError />
              </TextField>
              <TextField isRequired name="email" type="email">
                <Label>Email</Label>
                <Input placeholder="john@example.com" variant="secondary" />
                <FieldError />
              </TextField>
              <TextField
                isRequired
                name="bio"
                validate={(value) => {
                  if (value.length < 10) {
                    return "Bio must be at least 10 characters";
                  }

return null;
                }}
              >
                <Label>Bio</Label>
                <TextArea placeholder="Tell us about yourself..." variant="secondary" />
                <Description>Minimum 10 characters</Description>
                <FieldError />
              </TextField>
            </Fieldset.Group>
            <Fieldset.Actions>
              <Button type="submit">
                <FloppyDisk />
                Save changes
              </Button>
              <Button type="reset" variant="tertiary">
                Cancel
              </Button>
            </Fieldset.Actions>
          </Fieldset>
        </Form>
      </Surface>
    </div>
  );
}

```

### Anatomy

Import the Fieldset component and access all parts using dot notation.

```tsx
import { Fieldset } from '@blakeui/react';

export default () => (
  <Fieldset>
    <Fieldset.Legend />
    <Fieldset.Group>
      {/* form fields go here */}
    </Fieldset.Group>
    <Fieldset.Actions>
      {/* action buttons go here */}
    </Fieldset.Actions>
  </Fieldset>
)

```

## Related Components

- **TextField**: Composition-friendly fields with labels and validation
- **Label**: Accessible label for form controls
- **CheckboxGroup**: Group of checkboxes with shared state

## Styling

### Passing Tailwind CSS classes

```tsx
import { Fieldset, TextField, Label, Input } from '@blakeui/react';

function CustomFieldset() {
  return (
    <Fieldset className="rounded-xl border border-border bg-surface p-6 shadow-sm">
      <Fieldset.Legend className="text-lg font-semibold">Team members</Fieldset.Legend>
      <Fieldset.Group className="grid gap-4 md:grid-cols-2">
        <TextField>
          <Label>First name</Label>
          <Input className="rounded-full border-border/60" placeholder="Jane" />
        </TextField>
        <TextField>
          <Label>Last name</Label>
          <Input className="rounded-full border-border/60" placeholder="Doe" />
        </TextField>
      </Fieldset.Group>
      <Fieldset.Actions className="justify-end gap-3">
        {/* Action buttons */}
      </Fieldset.Actions>
    </Fieldset>
  );
}

```

### Customizing the component classes

Use the `@layer components` directive to target Fieldset [BEM](https://getbem.com/)-style classes.

```css
@layer components {
  .fieldset {
    @apply gap-5 rounded-xl border border-border/60 bg-surface p-6 shadow-field;
  }

.fieldset__legend {
    @apply text-lg font-semibold;
  }

.fieldset__field_group {
    @apply gap-3 md:grid md:grid-cols-2;
  }

.fieldset__actions {
    @apply flex justify-end gap-2 pt-2;
  }
}

```

### CSS Classes

The Fieldset compound component exposes these CSS selectors:

- `.fieldset` – Root container
- `.fieldset__legend` – Legend element
- `.fieldset__field_group` – Wrapper for grouped fields
- `.fieldset__actions` – Action bar below the fields
