Hi! We are creating a new website and I'm having some trouble with the downloads / resources section. When a visitor fills in a form, they are redirected to the PDF file which is an external URL. This completely closes our website. I do not want this behavior since I want the visitor to stay on our website. What I was thinking is once a visitor submits a form, the PDF opens in a separate tab, but then there's no thank you message after clicking on submit. What's the best way to manage this?
