Example uses:

  • finding flights departing on a particular day.
  • picking your date of birth for an online application form.


Basic Usage


Usage With All Props

  placeholder="Pick date"


  • componentId String unique identifier of the component, can be referenced in other components’ react prop.
  • dataField String data field to be connected to the component’s UI view.
  • nestedField String [optional] use to set the nested mapping field that allows arrays of objects to be indexed in a way that they can be queried independently of each other. Applicable only when dataField is a part of nested type.
  • title String or JSX [optional] title of the component to be shown in the UI.
  • defaultValue String [optional] selects initial date on mount.
  • value Array [optional] controls the current value of the component.It selects the date (on mount and on update).Use this prop in conjunction with onChange function.
  • onChange function [optional] is a callback function which accepts component’s current value as a parameter. It is called when you are using the value prop and the component’s value changes. This prop is used to implement the controlled component behavior.
  • focused Boolean [optional] whether to display the calendar view on initial load. Defaults to true.
  • numberOfMonths Number [optional] number of months to be shown in the calendar view. Defaults to 1.
  • initialMonth Date object [optional] if provided sets the initial visible month when nothing is selected and the calendar is pulled up. For example, passing new Date('2017-04-01') will open the calendar on January 1st, 2017.
  • queryFormat String [optional] sets the date format to be used in the query, can accept one of the following:

queryFormat Representation as elasticsearch date
epoch_millis (default) epoch_millis
epoch_second epoch_second
basic_time HHmmss.SSSZ
basic_time_no_millis HHmmssZ
date yyyy-MM-dd
basic_date yyyyMMdd
basic_date_time yyyyMMdd'T'HHmmss.SSSZ
basic_date_time_no_millis yyyyMMdd'T'HHmmssZ
date_time_no_millis yyyy-MM-dd'T'HH:mm:ssZZ
  • placeholder String [optional] placeholder to be shown in the field when no date is selected. Defaults to “Select Date”.
  • showClear Boolean [optional] displays a cross icon to clear the input value. Defaults to true.
  • clickUnselectsDay Boolean [optional] clears the selected date if an active date is selected in the calendar view. Defaults to true.
  • dayPickerInputProps object [optional] accepts an object which is passed to the underlying React Day Picker Input component. Find the props here.
  • showFilter Boolean [optional] show as filter when a value is selected in a global selected filters view. Defaults to true.
  • filterLabel String [optional] An optional label to display for the component in the global selected filters view. This is only applicable if showFilter is enabled. Default value used here is componentId.
  • URLParams Boolean [optional] enable creating a URL query string parameter based on the selected value of the list. This is useful for sharing URLs with the component state. Defaults to false.



DatePicker component supports innerClass prop with the following keys:

  • title
  • daypicker-container
  • daypicker-overlay-wrapper
  • daypicker-overlay

Read more about it here. This component uses React Day Picker Input which you may refer to in order to customize the calendar fully.


DatePicker component can be extended to

  1. customize the look and feel with className, style,
  2. update the underlying DB query with customQuery,
  3. connect with external interfaces using beforeValueChange, onValueChange and onQueryChange.
  style={{"paddingBottom": "10px"}}
    function(value, props) {
      return {
        query: {
          match: {
            data_field: "this is a test"
    function(value) {
      // called before the value is set
      // returns a promise
      return new Promise((resolve, reject) => {
        // update state or component props
        // or reject()
    function(value) {
      console.log("current value: ", value)
      // set the state
      // use the value with other js code
    function(prevQuery, nextQuery) {
      // use the query with other js code
      console.log('prevQuery', prevQuery);
      console.log('nextQuery', nextQuery);
  • className String CSS class to be injected on the component container.
  • style Object CSS styles to be applied to the DatePicker component.
  • customQuery Function takes value and props as parameters and returns the data query to be applied to the component, as defined in Elasticsearch Query DSL. Note: customQuery is called on value changes in the DatePicker component as long as the component is a part of react dependency of at least one other component.
  • beforeValueChange Function is a callback function which accepts component’s future value as a parameter and returns a promise. It is called everytime before a component’s value changes. The promise, if and when resolved, triggers the execution of the component’s query and if rejected, kills the query execution. This method can act as a gatekeeper for query execution, since it only executes the query after the provided promise has been resolved.
  • onValueChange Function is a callback function which accepts component’s current value as a parameter. It is called everytime the component’s value changes. This prop is handy in cases where you want to generate a side-effect on value selection. For example: You want to show a pop-up modal with the valid discount coupon code when a particular date is selected in a DatePicker.
  • onQueryChange Function is a callback function which accepts component’s prevQuery and nextQuery as parameters. It is called everytime the component’s query changes. This prop is handy in cases where you want to generate a side-effect whenever the component’s query would change.
