Input Datepicker

lion-input-datepicker component is based on the date text input field. Its purpose is to provide a way for users to fill in a date with a datepicker. For an input field with a big range, such as birthday-input, a datepicker is not the best choice due to the high variance between possible inputs. We encourage using the standard lion-input-date for this.

import { html } from 'lit-html';
import { MinMaxDate, IsDateDisabled } from '@lion/form-core';
import { loadDefaultFeedbackMessages } from '@lion/validate-messages';
import { formatDate } from '@lion/localize';

import './lion-input-datepicker.js';

export default {
  title: 'Forms/Input Datepicker',
};
loadDefaultFeedbackMessages();

export const main = () => {
  return html` <lion-input-datepicker label="Date" name="date"></lion-input-datepicker> `;
};

Minimum and maximum date

Below are examples of different validators for dates.

export const minimumAndMaximumDate = () => html`
  <lion-input-datepicker
    label="MinMaxDate"
    .modelValue=${new Date('2018/05/30')}
    .validators=${[new MinMaxDate({ min: new Date('2018/05/24'), max: new Date('2018/06/24') })]}
  >
    <div slot="help-text">
      Enter a date between ${formatDate(new Date('2018/05/24'))} and ${formatDate(
        new Date('2018/06/24'),
      )}.
    </div>
  </lion-input-datepicker>
`;

Disable specific dates

export const disableSpecificDates = () => html`
  <lion-input-datepicker
    label="IsDateDisabled"
    help-text="You're not allowed to choose any 15th."
    .validators=${[new IsDateDisabled(d => d.getDate() === 15)]}
  ></lion-input-datepicker>
`;

Calendar heading

You can modify the heading of the calendar with the .calendarHeading property or calendar-heading attribute for simple values.

By default, it will take the label value.

export const calendarHeading = () => html`
  <lion-input-datepicker
    label="Date"
    .calendarHeading="${'Custom heading'}"
    .modelValue=${new Date()}
  ></lion-input-datepicker>
`;

Disabled

You can disable datepicker inputs.

export const disabled = () => html`
  <lion-input-datepicker label="Disabled" disabled></lion-input-datepicker>
`;

Read only

You can set datepicker inputs to readonly, which will prevent the user from opening the calendar popup.

export const readOnly = () => html`
  <lion-input-datepicker label="Readonly" readonly .modelValue="${new Date()}">
  </lion-input-datepicker>
`;
