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 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, you'll need to add some custom code to your project. Here's a step-by-step guide on how to accomplish this:

1. Add the Google Places API Autocomplete library to your Webflow project:
- Go to the Google Cloud Console (https://console.cloud.google.com/).
- Create a new project (if you haven't already).
- Enable the Places API for your project.
- Generate an API Key for your project.
- Copy the API Key.

2. In your Webflow project, open the custom code settings:
- Go to your Webflow Designer.
- Click on the Project Settings icon in the left sidebar.
- Open the Custom Code tab.

3. Insert the following code into the Footer Code section of your project settings:
```html

```

Replace `YOUR_API_KEY` with the API Key you generated in step 1.

4. Add an input field to your form where you want the Google Place Autocomplete to appear:
- In your Webflow Designer, select the form element where you want to add the input field.
- Drag and drop an Input element onto the form.
- Give it a unique and meaningful class name (e.g., `autocomplete-input`).

5. Write a custom JavaScript code:
- Create a new JavaScript file (e.g., `autocomplete.js`) and save it in your project folder.
- In the JavaScript file, add the following code:
```javascript
document.addEventListener("DOMContentLoaded", function () {
var input = document.querySelector(".autocomplete-input");
var options = {
// Customize your Autocomplete options here
};

 var autocomplete = new google.maps.places.Autocomplete(input, options); // Validate on form submit var form = document.querySelector("form"); form.addEventListener("submit", function (e) {   if (input.value === "") {     e.preventDefault();     // Display an error message or style the input to indicate the error     alert("Please choose a location from the suggestions.");   } });

});
```

Customize the `options` object to configure the Autocomplete features as needed. Refer to the Google Places Autocomplete documentation for available options.

6. Link the JavaScript file to your Webflow project:
- In the Webflow Designer, click on the Project Settings icon in the left sidebar.
- Open the Custom Code tab.
- In the Footer Code section, add the following code:
```html

```

Replace `path/to/autocomplete.js` with the actual path to your `autocomplete.js` file within your project folder.

That's it! Now, when a user interacts with the input field, they will see suggestions from Google Place Autocomplete. If they try to submit the form without selecting one of the suggestions, they will be prompted with an error message. Remember to publish your project for the changes to take effect.
