In Webflow, how can I require that at least one option from a radio group be selected before submission?

To require that at least one option from a radio group be selected before submission in Webflow, you can follow these steps:

1. Open the Webflow Designer and navigate to the form element that contains the radio group you want to validate.
2. Select the radio group element by clicking on it.
3. In the right-hand panel, go to the "Settings" tab and scroll down to the "Validation" section.
4. Enable the "Require at least one choice" option by checking the corresponding checkbox.
5. Save your changes and publish your site for the changes to take effect.

By enabling the "Require at least one choice" option in Webflow, you are setting a validation rule that ensures the user must select at least one option from the radio group before they can submit the form. If no option is selected and the user tries to submit the form, an error message will be displayed, prompting them to select an option before they can proceed.

This validation feature is helpful for ensuring that users don't skip required fields in your forms and can improve the overall user experience of your website.

Note: This option is available for radio groups but not for checkboxes, as checkboxes allow users to select multiple options while radio groups only allow one option to be selected.
