UberMenu – Sticky Menu Extension
This plugin is an extension for UberMenu – WordPress Mega Menu Plugin
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 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.
