Hi Cliff!
Can you please share with us the link to your Wix site?
One of our WixCode team can inspect it and provide you with a solution.
Anyway, I imagine that you used " onViewportLeave( ) " and if not - thats a great way to do just that!
When you leave a certain area on the page (by scrolling) a certain action will take place.
And of course, the other way around - " onViewportEnter( ) ".
Just as I said, the other way around - When you enter a certain area on the page (by scrolling) a certain action will take place.
In this case, you should show / hide the menu accordingly.
Hope that helps.
Doron.
