Out of the box the animation is not possible within MUSE but a fullscreen menu is possible with a composition used with the lightbox mode.
Thankyou very much
As Uwe pointed out already, only simple kinds of animation aren‘t built into Muse. Here some examples, what is possible:

To create animations as your linked ones, you will have to look for 3rd party widgets. Just google for „Adobe Muse button animation“
I'll definately check, thanks for your help
is there any posibility by using html or css?
Ok, I'll try doing it by html, Thanks for the help.
