I am trying to produce a horizontal menu in WordPress that may be transformed quickly by non-technical customers without editing the theme directly. i.e. The graphics department :). I am a .internet developer and exactly how I'd do that insinternet is to produce a database using the characteristics from the link, making a easy to use back-finish to show the contents with CRUD.

Can there be an simpler method of carrying this out in WordPress?

I suppose you are creating a theme? Base your menu around the new default WordPress › TwentyTen theme's menu it's easily configurable drop lower CSS menus. For IE support, see http://firelords.net/wp-plugins/ie6-support-2010/ie6-support-2010.zip

You will find other plug ins, too, that offer easy menu generation within the Admin section for styles generally: CSS Dropdown search WordPress Plugins
