I have a lot of menu items in the main nav using the Decorous template. When people are viewing posts and they scroll down very far, the Decorous menu stays at the lowest menu items until the person scrolls all the way up the page. Is there a way to add a vertical scroll in the nav menu section so people can get to the nav item that they want quicker?
The menu could use the current behavior when the person uses the main scroll on the right side of the site, but if they want, they can use the new vertical nav scroll to go up the menu without going up the site. They might want to stay in the current position on the site, but only want to go up the menu so they don't lose their place after pressing the "load more" button a bunch of times.
The new menu scroll could also have css so it looks like part of the template.
