The Free Church Website is compose of Pure CSS and FS Menu. By the way I even used pure css round corner on this template.
Deluxe CSS Dropdowns and CSS Flyouts – this free CSS Menu, it used “sticky hovering zones” which ensure that the submenus stay open when moving between different level. This nav works in IE5, IE5.5, IE6, Op7, Gecko, Konqueror, and Safari. IEmac fails to support the hover method used, and so gets the expanded nav instead. IEwin with scripting disables also gets the expanded nav. Nav 4 does not support this method, or much else for that matter.
