First create a multiMenu 01 block and call it 'navbar'.
Make the following settings for a multi horizontal menu as can be seen
here:
Block format: 'CSS Drop down horizontal' / no. of columns 1
Block/D-Menu width: 120
Block height: 160
Random links: No
Link type to display: All
Do not set the cache of this block.
Add the following lines to the file theme.html of the theme you're using:
<div align="left">
<{foreach item=block from=$xoops_lblocks}>
<{if $block.title == 'navbar'}>
<{$block.content}>
<{/if}>
<{/foreach}>
div>
Now go to modules->multimenu->multiMenu 01.
Add a new link with type=mainlink and target=self. For subitems of this menu set type=note.
In your case:
2006 = mainlink
link2006-1 = note
link2006-2 = note
link2006-3 = note
2007 = mainlink
link2007-1 = note
link2007-2 = note
link2007-3 = note
2008 = mainlink
link2008-1 = note
link2008-2 = note
link2008-3 = note
You probably have to experiment with one of the css-files of multiMenu to get all style settings as you want.
