I am setting up a site and thought I had found a solution with multisite. However, as I've been reading through the setup, I'm not so sure.
I am setting up a network that has geographically based sub-sites. The parent site is a county level site and will contain all of the posts of the sub-sites, but not necessarily all of the pages. The child sites will contain posts that only pertain to their localities, although sometimes those posts will be shared with other localities. Each site - whether the county or local site - will have some of their own pages, but a few pages will be shared. Each site will also have their own headers and navigation. (They will link out to each other as part of the navigation for each site.) Sidebars/footers could be customized per site, too. However, all sites will be based from the same theme to share an overall look. Each site would also use its own domain name.
Because I will be one person managing all of these sites and because these sites will share posts, I want this to be managed as efficiently as possible.
Am I looking at using multisite or something else? The codex setup for multisite says this:
For example, if all you want is for different collections of web pages to look very different, then you can probably achieve what you want in a single site by using a plugin to switch themes, templates, or stylesheets.
Is this where I'm headed? Do I just need a plugin to switch templates per post? But won't that restrict me to using one template per post?
Any suggestions would be appreciated.
