How can I make it mandatory for users to choose one of the suggestions from Google Place Autocomplete before submitting a form on a landing page in Webflow?

To ensure users select an option from Google Place Autocomplete before submitting a form in Webflow, you'll need to integrate some custom JavaScript to validate the selection. Here’s how you can do that:

​

1. Set Up Google Places API

• Ensure your Google Places API is enabled in your Google Cloud account.
• Obtain an API key to use in your Webflow project.

​

2. Embed Autocomplete in Your Form

• Add a text input field in your Webflow form where users will type their location.
• Give this input field an ID for easy reference in your JavaScript code (e.g., location-input).

​

3. Add Custom JavaScript for Validation

• Navigate to your Project Settings and then to the Custom Code section.
• In the Before </body> tag area, add JavaScript code to handle Autocomplete and validation:
• Initialize Google Autocomplete: Use the Places API to initialize autocomplete on your input field.
• Validate Selection: Add event listeners that ensure a selection is made from the suggestions. An example would be disabling the submit button until a place is selected.

4. Handle Form Submission

• Use JavaScript to listen for submissions and prevent it if no suggestion has been selected:
• Check for valid place: Before allowing form submission, verify that the user's input corresponds to a listed Google Places suggestion.

​

5. Testing

• Test your form to ensure the autocomplete works and submission is only possible after selecting a suggestion.

​

Summary

To make your Webflow form's submission contingent on selecting a Google Place Autocomplete suggestion, use the Google Places API with custom validation JavaScript. This setup prevents forms from being submitted if users don't select an autocomplete suggestion, thereby ensuring data accuracy.
