I am trying to recreate something like this. I wan the menu to get go to the top and stay there when I scroll down and come back to its original position if I go scroll all the way to the top.
I would put this navbar and little top bar in the section with position: fixed.Then created interaction with scroll trigger, connected to the one of the objects under the navifation, but affecting that fixed section. Interaction would move the section up as much as it is needed for make navbar stick to the top of the page.
