CodeCanyon - Sticklr WP v1.3.0 - Sticky Side Panel WordPress Plugin | 533 KB
Stickr WP, a sticky side panel menu WordPress plugin. Inspired by Envato site-switcher, after released as CSS3 +jQuery, due to popular demand I decided to create this WordPress plugin version. The features are similar with jQuery version, only WordPress version has an intuitively easy administration panel, so you don't have to know the coding behind it.
