Third Level Page + Priority of 2nd level pages

[Connie]

Hi, as I am a newbie please forgive me when I did not find the answer myself or here in the forum ;=)

1)
I want to have second level pages which should not be included in the main menu (as I do not want a css-dropdown-menu)
so I use "get_navigation" for the first level menu and "child_pages" for the second level pages (if there are)
Now I see that it is not easy to define the priority of these pages when "add to menu" is unchecked...
I must check that first, define the priority of the 2ndlevel page, save and uncheck in the options again

that's somehow unlogical ...


2)
I want to define a third-level-page, so in the page-options I try to define the parent-page
but I do not see the 2ndlevelpages there

is this not possible
did I miss an option or do I need a plugin?

Cheers, Connie
