With the AllWebMenus Sliding Menu Add-in, you can create stylish menus with sliding submenus, otherwise known as "slide menus", "expandable menus", "collapsible menus" or "accordion menus". The AllWebMenus Sliding Menu Add-in allows you to create sliding menus where the subgroup will "hide" when not needed and "show" when necessary. In a user friendly way, you can create your web menus and set the submenu group to appear either as "drop-down" (non-sliding, standard menu mode) or as "sliding" (slide menu effect mode).
