What? There´s one scroll effect in your example with the kind menu/thumbs appearing after scroling up. What rest of the page?
If we talk about this website:
Yes, it is.
The line I marked appears when you start scrolling, even when you resize the browser.
How can I make this effect?
Or is it impossible by Muse?
For this you may need a "full height" widget, which is not possible with muse out of the box.
There are some HERO widgets out there from musethemes.com
You may have look at musewidgets.com to find something else.
Be aware that MUSE is under EOL, so it is your decision wether you to get part of a subscription based widgets vendor or not.
Thank you so much dear friend for paying time to answer.
I think the first link you sent, is like this link: http://www.scrolleffects.com/slideshow.html
and as you see, that is made with "Slide Show" in Muse itself.
But Slide Show does not do what I want.
And second link is another thing.
The thing I want is the same you saw in my original post.
I will search for another widgets.
All the best
