Fieldset

lion-fieldset groups multiple input fields or other fieldsets together.

import { html } from 'lit-html';
import '@lion/input/lion-input.js';
import { localize } from '@lion/localize';
import { loadDefaultFeedbackMessages } from '@lion/validate-messages';
import { MinLength, Validator, Required } from '@lion/form-core';
import './lion-fieldset.js';
import './docs/helpers/demo-fieldset-child.js';

export default {
  title: 'Forms/Fieldset/Overview',
};

We have three specific fieldset implementations:

• lion-form
• lion-checkbox-group
• lion-radio-group

export const main = () => html`
  <lion-fieldset name="nameGroup" label="Name">
    <lion-input name="FirstName" label="First Name"></lion-input>
    <lion-input name="LastName" label="Last Name"></lion-input>
  </lion-fieldset>
`;

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
• Can have validate on fieldset level and shows the validation feedback below the fieldset
• Can disable input fields on fieldset level
• Accessible out of the box
