Hello
I have a tab which come from the primary menu named "my_page".

The tab highlights (active css class) when I come to my_page, but, if I add some parameters for my module, it doesn't get highlighted anymore :-(

Example :
- link is content/my_page -> Access to content/my_page works perfect
- link in content/my_page/5/3 -> Tab is not active anymore

How can I tell Drupal to keep the tab active when I have some arguments ?

Thank for your help !
