Hello! I love the navigation bar that https://diagram.com/ has where a secondary navigation bar appears from the top of the viewport when the “magic wand” element is scrolled into view.
I implemented this onto my own website, but I’m having trouble hiding the navbar once I scroll up to a specific element.
Currently, the secondary navbar appears when the .portfolio_component is scrolled into view, offset by 50%.
I want the navbar to hide when I scroll up and reach the .portfolio_component element again. How do I implement this?
Thank you so much for your help
