# Form
[//]: # (AUTO INSERT HEADER PREPUBLISH)
`lion-form` is a webcomponent that enhances the functionality of the native `form` component. It is designed to interact with (instances of) the [form controls](../field/docs/FormFundaments.md).
## Features
- data synchronization with models
- easy retrieval of form data based on field names
- advanced validation possibilities
- advanced user interaction scenarios via [interaction states](../field/docs/InteractionStates.md)
- registration mechanism for [form controls](../field/).
- accessible out of the box
## How to use
### Installation
```sh
npm i --save @lion/form
```
```js
import '@lion/form/lion-form.js';
```
### Example
```html
<lion-form><form>
<lion-fieldset name="fullName">
<lion-input label="First Name" name="firstName" .modelValue=${model.firstName}></lion-input>
<lion-input label="Last Name" name="lastName" .modelValue=${model.lastName}></lion-input>
</lion-fieldset>
<lion-textarea label="Description" name="description" .modelValue=${model.description}></lion-textarea>
</form></lion-form>
```
