How can I disable the Webflow success or failure state for a sign-up form and display a custom thank you page using jQuery and the Webflow form submit state?

To disable the default success or failure state for a sign-up form in Webflow and display a custom thank you page using jQuery and the Webflow form submit state, you can follow these steps:

1. Create your custom thank you page: First, design and create your custom thank you page within your Webflow project. This page should have a unique URL.

2. Add jQuery: In your Webflow project, navigate to the page where your sign-up form is located. Open the page settings, click on the "Custom Code" tab, and paste the following code into the "Footer Code" section:

```html

```

This code will include the jQuery library in your project.

3. Disable Webflow form submit state: Still in the "Custom Code" tab, scroll down to the "Before " section and paste the following jQuery code:

```html

```

This code binds a function to the form's submit event, preventing the default form submission behavior. Inside the function, you can include your custom code to handle the form submission, such as AJAX requests for form data validation or sending the data to your server.

4. Update the "form" class: In your Webflow Designer, locate your sign-up form element and add the class "w-form" to it. This class is necessary for the jQuery code to target the form correctly.

5. Save and publish: After implementing the changes, save your project and publish it.

With these steps, when a user submits the sign-up form, the default success or failure states will be disabled. Instead, the form will trigger your custom code to handle the submission. Once the processing is complete, the user will be automatically redirected to your custom thank you page.

Remember to replace `'https://www.your-custom-thank-you-page-url.com'` with the actual URL of your custom thank you page. Additionally, you may need to customize the form submission handling code according to your specific requirements.
