When you use the Wizard layout and add multiple sections, you do not see a navigation option that lets you scroll through the sections. The navigation option lets you scroll through sections in the header if they do not fit in the space available on your screen.
If the navigation option is not available, include the following for elementNavigationChanged event in your client library:
window.guideBridge.on('elementNavigationChanged', function({guidelib.util.GuideUtil.showHideNavScroll();});
