I have read so many bits of documentation on overriding theme functions in my template.php and made various attempts but to be honest, I have just confused my self more and more and now I'm lost. Can someone lay it out for me, plain and simple what is required of me?
I want to assign some CSS to my primary links menu, but there are no unique identifiers on my primary links;. the first menu item naturally in Drupal is given class="expanded first active-trail" and the last has class="collapsed last" but the items in between are just class="collapsed". I want to apply some CSS to these top level headings (I'm thinking I could specify a class in the description field of each menu heading and then have my theme spit this out in the class="" bit?
As mentioned before I have been trying, and am failing so I wondered if someone could tell me from the top, so I understand correctly. I made a function in template.php, my_theme_name_links() which is a copy of theme_links() from theme.inc and made some changes, but they aren't having an effect on my menu links on my site (I have cleared the cache under Administer > Site Configuration > Performance). I made the same changes in the original theme_links() function in theme.inc (just to see it happen) and again, the changes aren't happening on my site. I'm very confused :(
