Is there a way to use WordPress Multisite to collaborate all subsites into the main site?
My thought is to have all the subsites to be departments of an organization and the main site be the front page for the organization. Navigation would be created automagically: one for the main site, then a separate navigation that would list the departments (subsites) with drop downs for the pages of those sites.
I’m sure this could all be scripted to work, but I’m curious if there’s a solution already out there to roll with right out of the box.
It’s definitely possible. And there are a few plugins to help make it easier
Diamon Multisite Widgets
WordPress MU Sitewide Tags
AFAIK there is no solution which works out of the box. It can be built using the WordPress blogs database table to get all active blogs. Using this you may get all pages per site and display them in a dropdown. This probably only works on sites with not too much subsites and pages.
