How can I configure Webflow forms to exclude empty or unchecked checkboxes when sending emails? Additionally, is it possible to customize the email text for checked checkboxes, such as using "réservé" instead of "true"?

To configure Webflow forms to exclude empty or unchecked checkboxes when sending emails, you'll need to use some custom code and adjust the form's submission settings. Here's a step-by-step guide:

1. Open your Webflow project, and navigate to the page with the form you want to modify.

2. Select the form element and go to the Settings panel on the right-hand side.

3. Under the Form Settings section, choose "Enable custom fields" and name each checkbox field accordingly.

4. Add the following code to your project's custom code settings (Site Settings > Custom Code > Footer Code):

```javascript

```

5. In the code snippet above, replace `'your-form-id'` with the actual ID of your form. You can find the form ID by selecting the form element, going to the Settings panel, and checking the Form ID field at the top.

6. If you want to customize the email text for checked checkboxes, locate the line with `'your-checkbox-field-name'` in the code. Replace `'your-checkbox-field-name'` with the actual name of your checkbox field where you want to use "réservé" instead of "true".

7. Save the changes and publish your site. Now, when the form is submitted, the code will exclude empty or unchecked checkboxes from the email and customize the text for checked checkboxes, if desired.

Note: Remember to test your form thoroughly to ensure it functions as expected. Also, keep in mind that this solution requires basic understanding of HTML and JavaScript.

I hope this helps! Let me know if you have any further questions.
