SharePoint 2010 pages and top navigation

SharePoint 2010 pages and show them dropdown in the navigation ith security trimming.

I want to see if there is a solution to show the navigation on top level bar navigation to show a dropdown of all the publishing pages on a site  and sub site on mouse over on site a and site c.
Home      site A         Site B          site C
      Page a            Page c
      Page a1            Page c1
      Page a2            Page c2


Not sub sites. Page a to a3 are SharePoint site pages. If there is solution please let me know.
I turned on publishing features on all sites  and sub sites.
For sub sites I am using team site and then tuned on publi8shing features.  The sub sites show up but not the pages under the site.
Any pointer is appreciated.
