Guys
new to C5, great tool.
Having some issues with making my header menu to display submenu when mouse rolls over it. saw a number of links here where guys are talking about replace header_nav with view.php and keeping the nav-header class, but for some reason it does not work for me.
can somebody please attach a sample of header nav php file where it works on your site and header menu displays the submenus on rollover?

Thank you so much
