# Example: Country sync

Use static getCountryData method to create a separate country dropdown for an address form, and then listen for change events to keep the two dropdowns in sync.

## Markup

    <div class="form-item">
      <label>Telephone number</label>
      <input id="phone" type="tel">
    </div>

    <div class="form-item">
      <label>Address</label>
      <input type="text" placeholder="House name/number">
      <input type="text" placeholder="City">
      <input type="text" placeholder="State">
      <input type="text" placeholder="Zip code">
      <select id="address-country"></select>
    </div>

## Code

    // get the country data from the plugin
    var countryData = window.intlTelInputGlobals.getCountryData(),
      input = document.querySelector("#phone"),
      addressDropdown = document.querySelector("#address-country");

    // init plugin
    var iti = window.intlTelInput(input, {
      utilsScript: "../../build/js/utils.js?1638200991544" // just for formatting/placeholders etc
    });

    // populate the country dropdown
    for (var i = 0; i < countryData.length; i++) {
      var country = countryData[i];
      var optionNode = document.createElement("option");
      optionNode.value = country.iso2;
      var textNode = document.createTextNode(country.name);
      optionNode.appendChild(textNode);
      addressDropdown.appendChild(optionNode);
    }
    // set it's initial value
    addressDropdown.value = iti.getSelectedCountryData().iso2;

    // listen to the telephone input for changes
    input.addEventListener('countrychange', function(e) {
      addressDropdown.value = iti.getSelectedCountryData().iso2;
    });

    // listen to the address dropdown for changes
    addressDropdown.addEventListener('change', function() {
      iti.setCountry(this.value);
    });

## Result

Telephone number
Address
