This library provides a pair of React components to display connected country and region dropdowns (pick a country, it shows the relevant regions). If you're not using React, check out the plain vanilla JS version instead. The list of countries and regions is maintained separately and found in the country-region-data repo.

Features

It's pretty versatile.

There are two separate components (<CountryDropdown />, <RegionDropdown>) that you can embed in your DOM wherever you need. That sounded like a vulgar euphemism, but it wasn't, honest.
The source data used by the library is also exposed, should you need it.
It let's you customize the list of countries that appears via a whitelist, blacklist.
A lot of options are provided, for things like styling, event callbacks and so on.
To keep file sizes down you have the option of creating a custom build of the library containing only a list of those countries you want to show up. See command line options for more info.

Gotchas

Page charset: some country names contain UTF-8 chars, so your page will need an appropriate charset to handle them. If you see some invalid characters appearing in the dropdown, make sure you have UTF-8 specified in your page <head>, like so: <meta charset="UTF-8">
Return values: on an onChange event event.target.value is returned as the first value and the full event as the second.

Demo

Check out the github pages section for some examples + example JSX code.

Installation

Using npm or yarn:

npm i react-country-region-selector
yarn add react-country-region-selector

Usage

It's very easy to use, but note that you will need to track the country and region value somewhere - either in your component state or in a store somewhere. Here's a simple example that uses state:

import React, { Component } from 'react';

// note that you can also export the source data via CountryRegionData. It's in a deliberately concise format to 
// keep file size down
import { CountryDropdown, RegionDropdown, CountryRegionData } from 'react-country-region-selector';


class Example extends Component {
  constructor (props) {
    super(props);
    this.state = { country: '', region: '' };
  }

  selectCountry (val) {
    this.setState({ country: val });
  }

  selectRegion (val) {
    this.setState({ region: val });
  }

  render () {
    const { country, region } = this.state;
    return (
      <div>
        <CountryDropdown
          value={country}
          onChange={(val) => this.selectCountry(val)} />
        <RegionDropdown
          country={country}
          value={region}
          onChange={(val) => this.selectRegion(val)} />
      </div>
    );
  }
}

Generally you don't need CountryRegionData, but if you should need it, the raw data is accessible like in the above example.

Options

These are the attributes that can be passed to the two components. Note: any other attributes that aren't specified here will be added directly to the <select> DOM element.

<CountryDropdown />

Parameter	Required?	Default	Type	Description
value	Yes	`""`	`string`	The currently selected country. This should either be the shortcode, or the full country name depending on what you're using for your value attribute (see the `valueType` option). By default it's the full country name.
onChange	Yes	`-`	`function`	Callback that gets called when the user selects a country. Use this to store the value in whatever store you're using (or just the parent component state).
onBlur	No	`-`	`function`	Callback that gets called when the user blurs off the country field.
name	No	`"rcrs-country"`	`string`	The name attribute of the generated select box.
id	No	`""`	`string`	The ID of the generated select box. Not added by default.
classes	No	`""`	`string`	Any additional space-separated classes you want to add.
showDefaultOption	No	`true`	`boolean`	Whether you want to show a default option.
priorityOptions	No	`array`	`[]`	Lets you target countries that should appear at the top of the dropdown. Should also be an array of country shortcodes.
defaultOptionLabel	No	`"Select Country"`	`string`	The default option label.
labelType	No	`"full"`	`string`	Either `"full"` or `"short"`. This governs whether you see country names or country short codes in the dropdown.
valueType	No	`"full"`	`string`	Either `"full"` or `"short"`. This controls the actual `value` attribute of each `<option>` in the dropdown. Please note, if you set this to `"short"` you will need to let the corresponding `<RegionDropdown />` component know as well, by passing a `countryValueType="short"` attribute.
whitelist	No	`[]`	`array`	This setting lets you target specific countries to appear in the dropdown. Only those specified here will appear. This should be an array of country shortcodes. See the country-region-data repo for the data and the shortcodes.
blacklist	No	`[]`	`array`	Lets you target countries that should not appear in the dropdown. Should also be an array of country shortcodes.
disabled	No	`false`	`boolean`	Disables the country field.

<RegionDropdown />

Parameter	Required?	Default	Type	Description
country	Yes	`""`	`string`	The currently selected country.
value	Yes	`""`	`string`	The currently selected region.
onChange	Yes	-	`function`	Callback that gets called when the user selects a region. Use this to store the value in whatever store you're using (or just the parent component state).
onBlur	No	-	`function`	Callback that gets called when the user blurs off the region field.
name	No	`"rcrs-region"`	`string`	The name attribute of the generated select box.
id	No	`""`	`string`	The ID of the generated select box. Not added by default.
classes	No	`""`	`string`	Any additional space-separated classes you want to add.
blankOptionLabel	No	`-`	`string`	The label that appears in the region dropdown when the user hasn't selected a country yet.
showDefaultOption	No	`true`	`boolean`	Whether you want to show a default option. This is what the user sees in the region dropdown after selecting a country. It defaults to the `defaultOptionLabel` setting (see next).
defaultOptionLabel	No	`Select Region`	`string`	The default region option.
onChange	No	`-`	`function`	Called when the user selects a region. Use this to store the region value.
countryValueType	No	`full`	`string`	If you've changed the country dropdown `valueType` to `short` you will need to set this value to `short` as well, so the component knows what's being passed in the `country` property.
labelType	No	`"full"`	`string`	Either `"full"` or `"short"`. This governs whether you see region names or region short codes in the dropdown.
valueType	No	`"full"`	`string`	Either `"full"` or `"short"`. This controls the actual `value` attribute of each `<option>` in the dropdown.
disableWhenEmpty	No	`false`	`boolean`	Disables the region field when the user hasn't selected a country.
disabled	No	`false`	`boolean`	Disables the region field. If set to true, it overrides `disableWhenEmpty`
customOptions	No	`[]`	`Array<string>`	Appends a list of string to the every region dropdown, regardless of the country selected.
whitelist	No	`{ CountryCode: [] }`	`object`	This setting lets you target specific regions to appear in the dropdown. Only those specified here will appear. This should be an array of region codes keyed by the country code.
blacklist	No	`{ CountryCode: [] }`	`object`	This setting lets you target specific regions that should not appear in the dropdown. This should be an array of region codes keyed by the country code.
disabled	No	`false`	`boolean`	Disables the region field. If set to true, it overrides `disableWhenEmpty`

Command-line

Check out the scripts section of the package.json file to see them all, but these are the highlights:

npm start - regenerate everything, plus a watcher for local development.
npm build - build the dist files again. No watcher.
rollup -c --config-countries=UK,US - generate a custom build of the script /dist folder containing only those countries you specify here. This seriously reduces file size, so if you can do it, do it.

Tests

The Jest/Enzyme unit tests are found in the src/tests folder. The repo is hooked up to Travis CI to automatically run the tests for each commit.

Local Dev

This is pretty dated, I'm afraid. But to run this locally, do the following:

npm install
in one terminal window: npm start
in another terminal window, go to the /example subfolder and do the same: npm install, npm start
open http://localhost:3000 in your browser.

Thanks!

Big thanks to a whole boatload of people:

contributors to this project and the source data.
Special thanks to the create-react-library tool which I use here (un-ejected) to rollup this component library. Great stuff.
