WordPress UberMenu Sticky Extension adds the ability to make your UberMenu “sticky”, meaning it’ll stick to the same spot in the viewport as your users scroll down your page.
Sticky menus for WordPress allow your users easy access to your menu at all times, without having to scroll back to the top of the page to navigate to a different part of your site. The Sticky Menu Extension will stick your menu in place even if it doesn’t start off at the top of your site, and hold it there while your users browse your content.
Please note that as this is an extension, it will not do anything without UberMenu installed.
UberMenu Sticky Menu Extension Features
By default, UberMenu Sticky Menu Extension is automatically disabled for mobile devices (phones, iPods, etc), since overflow content on fixed position menus will become inaccessible on small screens. It will continue to function as a sticky menu on larger devices, such as iPads, however.
UberMenu Sticky does have an experimental option for displaying sticky menus on mobile, which may work with your theme.
