it just a change in the CSS style. ( you may need js/ or CSS3 if you want that timed transition… but the lack of it would be too subtle to notice). Essentially what you need to do is change your LI UL. W/O going into specifics it would be something like:
#top-navi li ul { width: [width of your image]; background: url(yourImage.jpg) left bottom no-repeat #[some safe color]; min-height:[height-of your image];} #top-navi li li {background:none;} /possibli needed if you had assigned a background to your LI LI before/
html #top-navi li ul { height:height of your image];}/hack for older IE/
That, roughly is the gist of what the code should look like. Hope that helps
It’s using the jQuery hoverIntent plugin for the hover and menu open/close effect. So, if you disable javascript in the browser the menu will not drop down.
I searched out horizontal menus, but you know how that is, you’ll come back with a thousand sites to try to dig through. And of course searching the jQuery plugin site doesn’t return any type of preview. Is there a nickname for this specific style of horizontal navigation menu?
