GeoDistanceDropdown creates a location search based dropdown UI component that is connected to a database field. It is used for distance based filtering.

Example uses:

  • finding restaurants in walking distance from your location.
  • discovering things to do near a landmark.


Basic Usage

      { "distance": 20, "label": "< 20 miles" },
      { "distance": 50, "label": "< 50 miles" },
      { "distance": 100, "label": "< 100 miles" },

Usage With All Props

  title="Location Dropdown Selector"
      { "distance": 20, "label": "< 20 miles" },
      { "distance": 50, "label": "< 50 miles" },
      { "distance": 100, "label": "< 100 miles" },
    location: "London, UK"
    label: "< 100 miles"
  placeholder="Select a distance range.."


  • 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.
  • data Object Array collection of UI labels with associated distance value.
  • title String or JSX [optional] title of the component to be shown in the UI.
  • defaultValue Object [optional] pre-select values of the search query with label and location keys.
  • placeholder String [optional] set the placeholder to show in the location search box, useful when no option is defaultValue.
  • value Object [optional] controls the current value of the component. It sets the item from the list & also sets the location (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.
  • showIcon Boolean [optional] whether to display a search or custom icon in the input box. Defaults to true.
  • iconPosition String [optional] sets the position of the search icon. Can be left or right. Defaults to right.
  • icon JSX [optional] displays a custom search icon instead of the default 🔍
  • unit String [optional] unit for distance measurement, uses mi (for miles) by default. Distance units can be specified from the following: screenshot
  • autoLocation Boolean [optional] when enabled, preset the user’s current location in the location search box. Defaults to true.
  • 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 from the dropdown. This is useful for sharing URLs with the component state. Defaults to false.
  • countries String Array [optional] restricts predictions to specified country (ISO 3166-1 Alpha-2 country code, case insensitive). For example, ‘us’, ‘in’, or ‘au’. You can provide an array of up to five country code strings.
  • serviceOptions Object [optional] allows to add more options to AutoCompletionRequest, available from Google Places library

GeoDistanceDropdown 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.
  4. specify how options should be filtered or updated using react prop.
  5. add the following synthetic events to the underlying input element:

    • onBlur
    • onFocus
    • onKeyPress
    • onKeyDown
    • onKeyUp
    • autoFocus
  style={{"paddingBottom": "10px"}}
    function(location, distance, props) {
      return {
        // query in the format of Elasticsearch Query DSL
        geo_distance: {
          distance: distance + props.unit,
          location_dataField: location
    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 GeoDistanceDropdown component.
  • customQuery Function takes location, distance 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 GeoDistanceDropdown 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 every time 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 every time 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 within a specific location area.
  • 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.
  • react Object specify dependent components to reactively update GeoDistanceDropdown’s options. Read more about it here.

    • key String one of and, or, not defines the combining clause.

      • and clause implies that the results will be filtered by matches from all of the associated component states.
      • or clause implies that the results will be filtered by matches from at least one of the associated component states.
      • not clause implies that the results will be filtered by an inverse match of the associated component states.
    • value String or Array or Object

      • String is used for specifying a single component by its componentId.
      • Array is used for specifying multiple components by their componentId.
      • Object is used for nesting other key clauses.
