I am looking to create a sticky Nav, but I have a two-level header. I want the top part to disappear on scroll, but the bottom part to stay fixed to the top. Here is the link to the site I am building -> https://preview.webflow.com/preview/tdh-mechanical?preview=3dfc52e38652505370e9a02986df1ef6
Here is a link to a reference site -> https://michaelgould.com/
I was able to get the top to disappear and bottom stay sticky on mobile (max-width 600px)
Attached are two screenshots. One is my site now. One is the reference site on load and on scroll.
