Joey thank you very much for help. I made this to work but i like to be 
as much as user friendly as possible so one more question if it's not a 
problem. So, for now i did it like this:

Created field in pages tables called "menuroot" of type "Database 
relation". This gives BE user possibility to pick one page (this should 
be in fact the same page he edits). So this will be pageID for:

special.value.data = levelfield:-1, menuroot, slide

and this works fine.

What would be more user friendly is to put only a checkbox "Menu 
starting point" but then i should do something like:

if (levelfield:-1, menuroot, slide) == 1
   special.value = pageID_of_the_page_where_this_is_true

so i wonder if this is possible? Thx!

regards.
