I have exactly the same problem. I'm building a one-page-website using the template Nueva from the Brine-Family. I would like use the Navigation Bar to jump to the different sections in my stacked layout on my Index-Page. Is that possible at all?
If not, my work-around would be to use the Index-Navigation instead. But since on some pages there is only a picture (for a parallax effect between sections), which I don't want to appear in the navigation, that's also not the best solution at all. An alternative would be to make these picture only sections dispear in the Index-Navigation, but can't find out how to do that. Any suggestions?
