If anyone else wants to make the dropdown menus a little darker (less opaque).
After considerable time I have found the following –
The fast & easy method is to modify the opaque-color.png file.
If you want, you can modify the menu bar to match the new opaque color. It is in the style sheet
ja-sosdmenu.css
under #ja-cssmenu Around line 20 –
Add <blockquote>background: #yourcolor;
</blockquote>
Also, I found a bug in the original ja-sosdmenu.css sheet –
Around lines 121 and 125 change the file names from arrow-parent.gif and arrow-child.gif to arrow-on.gif and arrow-off.gif.
There are no parent and child gif files in my template?
Hope I can save someone else some time
