How can I set up a multi-step form in Webflow with radio button fields where at least one option is required to be selected before moving to the next slide?

To set up a multi-step form in Webflow with radio button fields and require at least one option to be selected before moving to the next slide, you can follow these steps:

1. Create a Form: Start by creating a form in Webflow by dragging and dropping the 'Form' element onto your page.

2. Add Form Fields: Within the form, add the necessary form fields, including radio button fields, for each step of the multi-step form.

3. Group Fields for Each Step: To create the steps, you need to group the form fields that belong to each step. You can use Webflow's 'Div' element to create separate sections for each step. Place the relevant form fields within each section.

4. Add Interaction Triggers: Select the first section containing the fields for the initial step. In the Webflow Designer, navigate to the Interactions panel. Click on the plus icon (+) to add a new interaction.

5. Set Up Interaction: In the interaction settings, select the 'Form Submission' trigger. Then, choose the 'Load' action. This action will determine the loading of the next step based on the form validation.

6. Configure Conditions: In the interaction settings, click on 'Only when...' to add a condition. You can set the condition to check if at least one radio button field in the current section is selected.

7. Repeat for Each Step: Repeat the above steps for each subsequent section of your multi-step form. Ensure that the interaction for each step is triggered after the previous step is validated.

8. Style the Form: Customize the styling of your form and its fields to match your desired design. You can use Webflow's style settings to change colors, fonts, sizes, and more.

9. Test and Publish: Preview your multi-step form within the Webflow Designer to ensure that the interactions and form validation are working correctly. Once everything looks good, publish your website for the changes to take effect.

By following these steps, you can set up a multi-step form in Webflow with radio button fields and enforce the requirement of selecting at least one option before progressing to the next step.
