You could either purchase the template at qooqee (this is not a recommendation), or try the use of state button out of the box from muse and pin those to the browsers bottom. However the transitions in between will not be that smooth but I am not sure if that is the most important issue here.
Better that the template you could do that responsive instead of adaptive (if you know what I mean).
If you start with muse right now and with a new project, be aware that Muse is under EOL by May 2020.
This should not panic you too much but good to know, I guess.
No there´s no real replacement for Muse right now - they all lack of something in comparison to Muse.
You might use another app with no coding necessary or try some coding apps like pinegrow or similar.
Or keep with Muse as long as possible, will be some more year or years to come. No-one really knows.
I put a quick and dirty MUSE here: menu-at-the-bottom
Be aware that the state button have their FOOTER checked.
Like this it only works with a fullscreen image. No pinning is necessary.
As soon as you wish to scroll up for a one page layout, you´ll have to pin.
It´s on BC, so don`t worry about the web address.
