Menu
Does anyone know how I can change the javascript so that the (below) menu displays horizontally instead of vertically?
[QUOTE=Ancora;533908]
Tested in IE6 and Firefox.
Hover on main menu items, sub-items are displayed.
Main menu items are not required to have sub items.
MenuTree.xml
[code]
<?xml version=”1.0″ ?>
<menu>
<main>
<text>First</text>
<sub>
<text>Anything</text>
<link>links/anything.html</link>
</sub>
<sub>
<text>Everything</text>
<link>links/everything.html</link>
</sub>
<sub>
<text>Nothing</text>
<link>links/nothing.html</link>
</sub>
</main>
<main>
<text>Second</text>
<link>links/apples.html</link>
</main>
<main>
<text>Third</text>
<sub>
<text>Something</text>
<link>links/something.html</link>
</sub>
</main>
<main>
<text>Fourth</text>
<link>links/oranges.html</link>
</main>
</menu>
