Developed by Tomas Bagdanavičius; CSS drop-down menu framework allows you to rapidly create fast loading, unobtrusive drop-down menus. You can use CSS Menu Framework to create horizontal, vertical left-to-right, vertical right-to-left, horizontal linear, and horizontal upwards menus. Most interestingly, you can transform your menu from one structure to another by simply changing a class name.
CSS Framework is modular – CSS definitions are categorized into structural and thematic types. Therefore in order to create a new drop-down menu you only need to create a new theme. Structural part is permanent and you don’t have to worry about it, unless you want to invent a new one.
