Highlight Menu Item when Scrolling Down to Section

I want to create a menu that is fixed and the items are highlighted based on the section that user is currently reading. How can I do that? I made combined components with the sections and when mouse enters that section the item in the menu to be highlighted. That works, however I can’t figure out how to make only the menu to be fixed and the sections to be scrollable.

Hi there, I hope I’m correctly understanding but I think you’d like to fix the specific frames and scroll others. In that case, please let me share some learning resources focusing on scrolling.

I hope you’ll be able to acheive your goal, but if you can’t please feel to reply again! If you can share some screenshots or screen recording so we can understand problem in detail, that would be appreciated too!
