# Fieldset >> Overview ||10

```js script
import { html } from '@mdjs/mdjs-preview';

import '@lion/input/define';
import '@lion/fieldset/define';
```

A web component that can be used to group multiple input fields or other fieldsets together.

```js preview-story
export const main = () => html`
  <lion-fieldset name="nameGroup" label="Name">
    <lion-input name="firstName" label="First Name" .modelValue=${'Foo'}></lion-input>
    <lion-input name="lastName" label="Last Name" .modelValue=${'Bar'}></lion-input>
  </lion-fieldset>
`;
```

We have three specific fieldset implementations:

- [form](https://github.com/ing-bank/lion/blob/650657231a4ec83592d45cd69836d28436635340/docs/components/form/overview.md)
- [checkbox-group](https://github.com/ing-bank/lion/blob/650657231a4ec83592d45cd69836d28436635340/docs/components/checkbox-group/overview.md)
- [radio-group](https://github.com/ing-bank/lion/blob/650657231a4ec83592d45cd69836d28436635340/docs/components/radio-group/overview.md)

A native fieldset element should always have a legend-element for a11y purposes.
However, our fieldset element is not native and should not have a legend-element.
Our fieldset instead has a label attribute or you can add a label with a div- or heading-element using `slot="label"`.

## Features

- Easy retrieval of form data based on field names
- Advanced user interaction scenarios via [interaction states](https://github.com/ing-bank/lion/blob/650657231a4ec83592d45cd69836d28436635340/docs/fundamentals/systems/form/interaction-states.md)
- Can have [validate](https://github.com/ing-bank/lion/blob/650657231a4ec83592d45cd69836d28436635340/docs/fundamentals/systems/form/validate.md) on fieldset level and shows the validation feedback below the fieldset
- Can disable input fields on fieldset level
- Accessible out of the box
