currenty the slider can display posts of a certain category only and it will link to the posts automatically. It’s not easily possible to change this behaviour without rewriting major parts of the slider code.
Hmm that’s to bad. However, I’ve read your reply and tested some other things before this reply.
I tried it with a redirect, and it even though it’s not the ideal solution it works too. I now have the redirect pointing to a full width page. One of the advantages of doing it like this is that you can still use text in the slider that isn’t visible on the page.
