I've had this issue numerous times on sites using drupal and not really found a way that feels right when building menus. Take an example such as this
Primary Navigation [i.e. top of the page]
- Item 1
- Item 2
- Item 3
- Item 4
- Item 5
Then within each Item there would be a secondary menu specific to it:
Item 1 Pages
- Link 1
- Link 2
- Link 3
Item 2 Pages
- Link 1
- Link 2
- Link 3
The links on item 1 and item 2 are not the same, thus they have to be independant of each other.
I think it's standard navigation for site, primary navigation and localised secondary navigation.
What is the "Drupal" (or correct?) way of doing this?
