Date Picker

Playbook's date picker is built using flatpickr, a vanilla js library. Common date picker use cases and features have been adapted into simple prop based configuration detailed in the docs below. You can implement additional features and functionality by accessing a flatpickr instance directly (demonstrated in the 'flatpickr methods' example below). This is done with the following code.

const fpInstance = document.querySelector('#pickerId')._flatpickr

pickerId is a prop passed to the date picker kit. Flatpickr uses this id to target an input and attach a flatpickr instance to that input.

To learn more visit flatpickr's docs or see the hook doc section below for an applied example.

The Date Picker works best with Javascript Date Objects or ISO Date strings. If you're programming in js use Date Objects. If you're using rails convert your date object (with timezone) to UTC and then to an ISO Date string. For example, DateTime.now.utc.iso8601. This ensures that the string passed to the Date Picker kit behaves as expected.

Default Date

The defaultDate/default_date prop has a null or empty string value by default. You can pass an ISO date string (preferred rails method) or date object (preferred JS method) if you want a default value on page load. Use Ruby UTC DateTime objects and convert them to ISO date strings with DateTime.now.utc.iso8601.

If you use a Date object without UTC time standardization the Date Picker kit may misinterpret that date as yesterdays date (consequence of timezone differentials and the Javascript Date Object constructor). See this GitHub issue for more information and the anti-pattern examples below.

Allow Input

Setting the allowInput prop to true permits users to key values directly into the input. This prop is set to false by default.

Input Field

The date picker is built with the text input kit. Text input props you pass to the date picker kit will be forwarded to the input, with a few exceptions. The value attribute is automatically handled and bound to whatever date string is contained by the input field. You cannot pass a custom value prop. id props passed to the date picker kit will be assigned to it's parent/wrapper div. The pickerId prop is passed directly to the input and is required to instatiate the date picker.

You must use inputAria or input_aria and inputData or input_data props if you wish to pass data or aria attributes to the text input kit. If you use data or aria props they will be passed to the date picker kit itself instead. Also be aware the default behavior of text input aria and data props is to pass those props to attributes on the wrapping div not on the input itself.

The placeholder prop has a default string value: "Select Date". You can replace this with your own string or an empty string if you'd prefer it blank.


Default label prop is "Date Picker". To remove the label set the hideLabel prop in React or the hide_label prop in Rails to true.


Your change handler function has access to two arguments: dateStr and selectedDates.

The first, dateStr, is a string of the chosen date. The second, selectedDates, is an array of selected date objects. In many use cases selectedDates will have only one value but you'll still need to access it from index 0.

Flatpickr Methods


You can find a full list of flatpickr events and hooks in their documentation.

Year Range

Defaults to [1900, 2100]. Combine with min-max prop for best results.


Month & Year Only

By default selectType prop is disabled. To activate it set selectionType prop in JSX/TSX to month. To activate it set selection_type prop in a rails file to month.


By default selectType prop is disabled. To activate it set selectionType prop in JSX/TSX to week. To activate it set selection_type prop in a rails file to week.

Time Selection

To select time as well, you should pass the enableTime boolean prop. You can also enable timezone display by passing showTimezone.

Custom Positions

Datepicker supports position options from Flatpickr Options Documentation. There are multiple positioning options to choose from.

Note: In order for the above prop to work properly, you must also send staticPosition={false} to your Datepicker kit instance.

Affix Datepicker Upon Scrolling

Upon adding static={false} to the date picker, you will notice that the date picker detaches from the input field while scrolling. This is a known Flatpickr nuance. By adding the scrollContainer prop, you can tell the date picker which DOM container it should watch for scroll events. In this example, you can see that scrollContainer=".pb--page--content--main" is being passed in order to keep the date picker correctly positioned on page scroll.

Useage: scrollContainer: .validQuerySelectorHere
