Hello Patrick,

Thank you for getting in touch with us. My name is Andrea, and I'm happy to assist you today. 

You would be please to show me an example of what you want to create? Is there a website where you have seen such kind of animation you want?

Please specify what you want to achieve: do you want to display a website inside the slide, do you want to display a website in a modal window, or do you want to make a linkable button? In this last case, you can find information about the how to make it:
