Overview

The Date Picker is a combination of the Date Field , Calendar , and Popover . It's fully accessible, and works with all modern browsers & devices.

Before jumping into the docs for this builder, it's recommended that you understand how we work with dates & times in Melt, which you can read about here . Additionally, since this builder simply combines other builders, it's recommended that you read the docs for those builders as well.

Anatomy

  • Field: The element which contains the date segments
  • Segment: An individual segment of the date (day, month, year, etc.)
  • Label: The label for the date field
  • Hidden Input: A hidden input element containing the value of the field
  • Validation: The container for the validation message
  • Calendar: The container of the months and days of the calendar
  • Cell: A single date in the calendar
  • Grid: A month in the calendar
  • Previous Button: A button for navigating to the previous page of the calendar
  • Next Button: A button for navigating to the next page of the calendar
  • Heading: A visual heading for the calendar
  • Trigger: The button which opens/closes the popover.
  • Content: Contains the content within the popover
  • Arrow: An optional arrow component

Scaffold a Date Picker

This section is designed to help you get started with the correct markup for a date picker. Since it's a combination of three other builders, there are a lot of working parts. This section will help you understand how to bring them all together, though it's highly recommended you read the docs for the Date Field , Calendar , and Popover builders as well.

Let's start by initializing our date picker using the createDatePicker function and destructuring the pieces we need:

    <script lang="ts">
  import { createDatePicker } from '@melt-ui/svelte'
 
  const {
    elements: {
      calendar,
      cell,
      content,
      field,
      grid,
      heading,
      label,
      nextButton,
      prevButton,
      segment,
      trigger
    },
    states: { months, headingValue, weekdays, segmentContents },
    helpers: { isDateDisabled, isDateUnavailable }
  } = createDatePicker()
</script>
	
    <script lang="ts">
  import { createDatePicker } from '@melt-ui/svelte'
 
  const {
    elements: {
      calendar,
      cell,
      content,
      field,
      grid,
      heading,
      label,
      nextButton,
      prevButton,
      segment,
      trigger
    },
    states: { months, headingValue, weekdays, segmentContents },
    helpers: { isDateDisabled, isDateUnavailable }
  } = createDatePicker()
</script>

Next, we can setup our field. Notice that in addition to the segments that we normally add to a Date Field , we also add a trigger button for the Popover .

    <span use:melt={$label}>Appointment Date</span>
<div use:melt={$field}>
  {#each $segmentContents as seg}
    <div use:melt={$segment(seg.part)}>
      {seg.value}
    </div>
  {/each}
  <div>
    <button use:melt={$trigger}>
      <span>Open Calendar</span>
    </button>
  </div>
</div>
	
    <span {...$label} use:label>Appointment Date</span>
<div {...$field} use:field>
  {#each $segmentContents as seg}
    <div {...$segment(seg.part)} use:segment>
      {seg.value}
    </div>
  {/each}
  <div>
    <button {...$trigger} use:trigger>
      <span>Open Calendar</span>
    </button>
  </div>
</div>

Once that's in place, we can setup our calendar, which will be contained within the Popover 's content.

    <span use:melt={$label}>Appointment Date</span>
<div use:melt={$field}>
  {#each $segmentContents as seg}
    <div use:melt={$segment(seg.part)}>
      {seg.value}
    </div>
  {/each}
  <div>
    <button use:melt={$trigger}>
      <span>Open Calendar</span>
    </button>
  </div>
</div>
<div use:melt={$content}>
  <div use:melt={$calendar}>
    <header>
      <button use:melt={$prevButton}>
        <span>Previous Month</span>
      </button>
      <div use:melt={$heading}>
        {$headingValue}
      </div>
      <button use:melt={$nextButton}>
        <span>Next Month</span>
      </button>
    </header>
    {#each $months as month}
      <table use:melt={$grid}>
        <thead aria-hidden="true">
          <tr>
            {#each $weekdays as day}
              <th>
                {day}
              </th>
            {/each}
          </tr>
        </thead>
        <tbody>
          {#each month.weeks as days}
            <tr>
              {#each days as date}
                <td
                  role="gridcell"
                  aria-disabled={$isDateDisabled(date) || $isDateUnavailable(date)}>
                  <div use:melt={$cell(date, month.value)}>
                    {date.day}
                  </div>
                </td>
              {/each}
            </tr>
          {/each}
        </tbody>
      </table>
    {/each}
  </div>
</div>
	
    <span {...$label} use:label>Appointment Date</span>
<div {...$field} use:field>
  {#each $segmentContents as seg}
    <div {...$segment(seg.part)} use:segment>
      {seg.value}
    </div>
  {/each}
  <div>
    <button {...$trigger} use:trigger>

      </div>
      <button {...$nextButton} use:nextButton>
        <span>Next Month</span>
      </button>
    </header>
    {#each $months as month}
      <table {...$grid} use:grid>
        <thead aria-hidden="true">
          <tr>
            {#each $weekdays as day}
              <th>
                {day}
              </th>
            {/each}
          </tr>
        </thead>
        <tbody>
          {#each month.weeks as days}
            <tr>
              {#each days as date}
                <td
                  role="gridcell"
                  aria-disabled={$isDateDisabled(date) || $isDateUnavailable(date)}>
                  <div {...$cell(date, month.value)} use:cell>
                    {date.day}
                  </div>
                </td>
              {/each}
            </tr>
          {/each}
        </tbody>
      </table>
    {/each}
  </div>
</div>

And with those pieces in place, we just need to add some styles and we have a fully functional date picker.

Placeholder

In this section, we'll learn about the placeholder props, which are used to change what type of value the field represents, and what day the calendar displays when no date is selected.

To learn more about how the placeholder affects the different parts of the date picker, checkout the placeholders docs for the Date Field & Calendar builders.

Set the Placeholder Date

The Date Picker has two placeholder props, placeholder (controlled), and defaultPlaceholder (uncontrolled), which are used to change how the field segments are rendered, and what is first displayed in the calendar when no date is selected.

By default, the placeholder will be set to a CalendarDate object with current date (and no time), but you can override this by passing any DateValue object to the defaultPlaceholder prop.

Below, we'll set the placeholder to a CalendarDateTime object representing February 1st, 2021.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDateTime } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    defaultPlaceholder: new CalendarDateTime(2021, 2, 1)
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDateTime } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    defaultPlaceholder: new CalendarDateTime(2021, 2, 1)
  })
</script>

Although we didn't include a time when instantiating the CalendarDateTime object, the builder is smart enough to know that the date picker should represent a date and a time, and will render the appropriate segments.

When a time isn't included with a CalendarDateTime object, the time will default to 00:00:00.000 on that date.

Values

The Date Picker has two value props, value (controlled), and defaultValue (uncontrolled), which are used to determine what date the field is populated with, and what day is selected in the calendar popover.

Setting a Default Value

To have a date selected by default, we can use either value prop. Below, we'll set the defaultValue to a CalendarDate of January 11, 2024.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    defaultValue: new CalendarDate(2024, 1, 11)
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    defaultValue: new CalendarDate(2024, 1, 11)
  })
</script>

And as the example below demonstrates, the field is populated with the date, and the calendar has that date selected.

Using the Value Store

The value store returned from the createDatePicker function is a writable store containing a DateValue object with whatever type of date was passed via the placeholder or value props.

You can use this value to display the selected date in your markup somewhere, or to perform some action when the value changes.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
    states: { value /* ... */ }
  } = createDatePicker({
    defaultValue: new CalendarDate(2024, 1, 11)
  })
</script>
 
<span>You Selected: {$value}</span>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
    states: { value /* ... */ }
  } = createDatePicker({
    defaultValue: new CalendarDate(2024, 1, 11)
  })
</script>
 
<span>You Selected: {$value}</span>

Usage with Forms

It's likely that you'll want to use the Date Picker in an HTML form, and to do that, you'll want to use the hiddenInput element that's returned from the createDatePicker function.

The hiddenInput element is a hidden input element that contains an ISO 8601 string of the value of the field, and is updated whenever the value changes.

If you do plan on using the hiddenInput, ensure that you set the name prop, as it will be used as the name of the input element.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
    elements: { hiddenInput /* ... */ }
  } = createDatePicker({
    name: 'appointmentDate'
  })
</script>
 
<span use:melt={$label}>Appointment Date</span>
<div use:melt={$field}>
  {#each $segmentContents as seg}
    <div use:melt={$segment(seg.part)}>
      {seg.value}
    </div>
  {/each}
  <div>
    <button use:melt={$trigger}>
      <span>Open Calendar</span>
    </button>
  </div>
  <input use:melt={$hiddenInput} />
</div>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
    elements: { hiddenInput /* ... */ }
  } = createDatePicker({
    name: 'appointmentDate'
  })
</script>
 
<span {...$label} use:label>Appointment Date</span>
<div {...$field} use:field>
  {#each $segmentContents as seg}
    <div {...$segment(seg.part)} use:segment>
      {seg.value}
    </div>
  {/each}
  <div>
    <button {...$trigger} use:trigger>
      <span>Open Calendar</span>
    </button>
  </div>
  <input {...$hiddenInput} use:hiddenInput />
</div>

Appearance & Behavior

Fixed Weeks

By default, the calendar will render as many weeks as it needs to display all of the days in that month. However, if you want the calendar to always render the maximum number of weeks (6), you can set the fixedWeeks prop to true.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    fixedWeeks: true
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    fixedWeeks: true
  })
</script>

Now, regardless of the month, the calendar will always render 6 weeks, so there isn't a jump in the UI when navigating between different sized months.

Multiple Months

By default, the calendar will display one month, but you can change this by setting the numberOfMonths prop.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    numberOfMonths: 2
  })
</script>
	
    <script lang="ts">

  const {
    /* ... */
  } = createDatePicker({
    numberOfMonths: 2
  })
</script>

Paged Navigation

By default, when the calendar has more than one month, the previous and next buttons will shift the calendar forward or backward by one month. However, you can change this behavior by setting the pagedNavigation prop to true, which will shift the calendar forward or backward by the number of months being displayed.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    numberOfMonths: 2,
    pagedNavigation: true
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    numberOfMonths: 2,
    pagedNavigation: true
  })
</script>

Localization

The date picker will automatically format the content of the field & calendar according to the locale prop, which defaults to 'en-US', but can be changed to any locale supported by the Intl.DateTimeFormat constructor.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    locale: 'es'
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    locale: 'es'
  })
</script>
Date

/

Prevent Deselection

By default, users can deselect a selected date without selecting another, by selecting the date again. This results in the value potentially being undefined. If you'd like to disable this behavior, you can set the preventDeselect prop to true, which will prevent the user from being able to deselect dates.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    preventDeselect: true
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    preventDeselect: true
  })
</script>

Now the user is unable to deselect a date without selecting another in the calendar. Note, the user can still clear the field by deleting the value in the field, this only handles the calendar behavior.

Validation

Although possible to implement your own logic using change functions , the Date Picker provides a few props that make it a bit easier.

Unavailable Dates

An unavailable date is a date that is not selectable, but is still visible and focusable in the calendar.

You can pass a Matcher function to the isDateUnavailable prop, which will be used to determine if a date is unavailable. The Matcher function is called with a DateValue object, and should return a boolean indicating whether the date is unavailable.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { isWeekend } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    isDateUnavailable: (date) => {
      return isWeekend(date, 'en')
    }
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { isWeekend } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    isDateUnavailable: (date) => {
      return isWeekend(date, 'en')
    }
  })
</script>

The unavailable dates will have the data-unavailable attribute set, which you can use to style differently than the other dates.

Disabled Dates

Disabled dates are not selectable, nor are they focusable in the calendar. Keyboard navigation will skip over them entirely, and should be used for dates that have no meaning in the context of the calendar.

You can pass a Matcher function to the isDateDisabled prop, which will be used to determine if a date is disabled. The Matcher function is called with a DateValue object, and should return a boolean indicating whether the date is disabled.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    isDateDisabled: (date) => {
      return date.day <= 10
    }
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
 
  const {
    /* ... */
  } = createDatePicker({
    isDateDisabled: (date) => {
      return date.day <= 10
    }
  })
</script>

In this example, we're disabling the first 10 days of each month.

Minimum & Maximum Values

While the isDateDisabled prop is useful for more complex logic, the Date Picker also provides the minValue and maxValue props, which are used to set the min and max selectable dates, which is nice if you're just trying to limit the range of dates that can be selected.

If a date is before the minValue, or after the maxValue, it will be disabled.

    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    minValue: new CalendarDate(2023, 1, 15),
    maxValue: new CalendarDate(2023, 2, 15)
  })
</script>
	
    <script lang="ts">
  import { createDatePicker, melt } from '@melt-ui/svelte'
  import { CalendarDate } from '@internationalized/date'
 
  const {
    /* ... */
  } = createDatePicker({
    minValue: new CalendarDate(2023, 1, 15),
    maxValue: new CalendarDate(2023, 2, 15)
