We decided to create this script when we needed a compact CSS drop down menu for a project. Chrome Menu is a CSS and JavaScript hybrid drop down menu. It's easy to configure and search engine friendly. The menu links is based on a list, while the drop down menus are simply regular DIV tags on page. Thanks to JavaScript, the menu supports subtle but important effects such as delay before menu disappearance, and repositioning of the menu if too close to any one of the four corners of the window. The entire menu, including images and external files, is extremely compact, at around 6 kilobytes.
