1. Flyout menu for sub-items on main navigation gets cut off or doesn't show on screen when you shrink the browser window. Please let me know how to fix this.
2. When I check the navigation menu on my mobile phone, the menu appears as a long list of menu items, without any indication of sub-items. This is quite jarring as there are many items and makes it very confusing for a user to navigate. Can you let me know if there's a way to fix this?
3. I fixed the top navigation menu to stick at the top as you scroll down the page. However, the navigation menu disappears until you scroll down to half the page. How can I make it stick?
