I think there is limited flexibility here. I remade the slider on the home page – https://makingyour.site/supportsurvey/ – but I had to make 2 sliders, because of the layout having a bottom full-width bar. The only way to make this look like it is working is to remove the navigation, remove the drag feature and remove the pause on hover, otherwise, the 2 sliders go out of sync.
I think that it would be amazing if we could create a template (as I have, but it doesn’t work correctly as you mentioned above), and have it wrapped into an inner section. Please let me know if you think there is another way I could accomplish this layout using your slider tool.
