# Display Address in One Line

Instead of writing each address attributes to individual fields, you may exercise fine control about how address data is presented using the [`onAddressRetrieved`](https://address-finder.ideal-postcodes.co.uk/interfaces/Controller.ControllerOptions.html#onAddressRetrieved) callback.

In this example, we merge the addresses and insert it to a `textarea`.

<form style="max-width: 450px; padding: 10px;">
  <label for="input">Search Your Address</label>
  <input type="text" id="input" placeholder="Start typing address here" />
  <label for="output_field">Address Output:</label>
  <pre id="output_field"></pre>
</form>

import { AddressFinder } from "@ideal-postcodes/address-finder";

AddressFinder.setup({
  apiKey: "ak_test",
  inputField: "#input",
  onAddressRetrieved: (address) => {
    const result = [
      address.line_1,
      address.line_2,
      address.line_3,
      address.post_town,
      address.postcode,
    ]
      .filter((elem) => elem !== "")
      .join("\n");
    document.getElementById("output_field").textContent = result;
  },
