In this mode ReDoc shows initial screen ASAP and then renders the rest operations asynchronously while showing progress bar on the top. Check out the [demo](\\redocly.github.io/redoc) for the example.~~
 * `menuToggle` - if true clicking second time on expanded menu item will collapse it, default `true`.
 * `nativeScrollbars` - use native scrollbar for sidemenu instead of perfect-scroll (scrolling performance optimization for big specs).
