MultiDropdownRange component can be extended to

  1. customize the look and feel with style,
  2. update the underlying DB query with customQuery,
  3. connect with external interfaces using beforeValueChange, onValueChange and onQueryChange
  style={{ paddingBottom: 10 }}
    function(value, props) {
      return {
        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);
  • style Object CSS styles to be applied to the MultiDropdownRange 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 MultiDropdownRange 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 user searches for something in the MultiDropdownRange.
  • 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.
