This plugin is just designed to create a list of all sites in a multisite network. You may include or exclude individual sites plus whether to have them provide a link to the blog or not.
The below list is just a simple list with the sites not having a link. This is the default setting.
[blog_menu]
Now with a link to the blogs.
[blog_menu link-to-blog='true']
This shortcode will only include blogs with id’s of 2 and 3.
[blog_menu link-to-blog='true' include_blog='2,3']
This will show all blogs except for blog 2.
[blog_menu link-to-blog='true' exclude_blog='2']
You may also show it as a drop down using the following.
[blog_menu link-to-blog='true' show-as-dropdown='true']
By default it doesn’t look very pretty. So with some custom css the dropdown menu may look more attractive.
