Installation

Create Address Inputs

Address Inputs are created using Input fields under Forms. However, Webflow requires you to to create a Form Block first. This is also found in the same section. A basic address form to capture a correct UK address requires the following fields:

• Address line one
• Address line two
• Address line three
• Post town
• Postcode

note

Take note of your input IDs you will need them later to configure Address Finder or Postcode Lookup. These can be found in field settings

Initialise Address Finder

Insert Code

Add an Embed Code component at the bottom of your form to add the Address Finder script.

<script src="https://cdn.jsdelivr.net/npm/@ideal-postcodes/address-finder-bundled@4"></script>

<script>
  document.addEventListener("DOMContentLoaded", function () {
    IdealPostcodes.AddressFinder.setup({
      apiKey: "ak_test",
      outputFields: { 
        line_1: '#field-1', 
        line_2: '#field-2', 
        line_3: '#field-3', 
        post_town: '#field-4', 
        postcode: '#field-5' 
      }
    });
  });
</script>

caution

Take special care to:

1. Insert your API Key in the apiKey field
2. Match the names of your input fields.

Add Postcode Lookup

Layout

Add an Embed Code component at the top of your form. Copy the following:

<div>
<!-- Postcode search field will appear below -->
  <div>
    <input 
      type="text" 
      placeholder="Lookup your postcode"
      id="idpc_input" 
    />
  </div>
  <!-- Search button will appear below -->
  <div>
    <input 
      type="button" 
      id="idpc_button" 
      value="Lookup Postcode" 
    />
  </div>
  <!-- Address dropdown field will appear below -->
  <div id="idpc_dropdown"></div>
  <!-- Any error messages will appear here -->
  <div id="idpc"></div>
</div>

Initialise Postcode Lookup

Create another Embed Code component at the bottom of the form and add the script below:

<script 
  src="https://cdn.jsdelivr.net/npm/@ideal-postcodes/postcode-lookup-bundled@2/dist/postcode-lookup.js">
</script>

<script>
  IdealPostcodes.PostcodeLookup.setup({
    context: '#idpc',
    input: '#idpc_input',
    button: '#idpc_button',
    selectContainer: '#idpc_dropdown',
    selectClass: 'select-field',
    apiKey: "ak_test",
    outputFields: { 
      line_1: '#field-1', 
      line_2: '#field-2', 
      line_3: '#field-3', 
      post_town: '#field-4', 
      postcode: '#field-5' 
    }
  });
</script>

caution

Take special care to:

1. Insert your API Key in the apiKey field
2. Match the names of your input fields.
3. Ensure the context string matches the id of <div id="idpc"></div>, the line of code should read context: "#idpc"
