You can make a Webflow form submit button open in a new tab after redirection by adding a small custom JavaScript snippet to your page. Webflow’s built-in redirect settings do not provide a way to open the redirect in a new tab, but this workaround will handle it.
Go to Page Settings in Webflow.
Scroll down to the Custom Code section.
Under Footer Code, insert the following script:
```html
```
Webflow doesn’t offer a default setting for opening a redirect URL in a new tab after form submission. However, by adding a JavaScript snippet to intercept the form submission and open the redirect in a new tab, you can achieve this functionality.
