@sriotti and anyone else interested: I finally added some simple multi-page examples to our repo like I’ve been promising for a long time. Check them out here. They include a navbar example, plus multiple sidebar examples, including collapsible submenus and responsive designs. Try running them or check out some screenshots on the pull request.
Also more generally, the release of Dash 0.41.0 let us add some cool new features. Personally I’m pretty excited about the new Modal component, which lets you easily add modals to your apps without having to fiddle around with CSS and z-indexes. Check out the steadily improving documentation or our repo to see the new stuff we’re adding.
