As this manual is for both Joomla and Wordpress. Please read usergroup as siterole and vice versa. Screenshots are taken at random per CMS.
The plugin has a built-in function to redirect a particular usergroup to a specific menu item after each login.
In the above single select example we have set each group to redirect to a separate menu item upon login. Silent usergroups should remain to "set default".
Be aware that you can only redirect a user to one menu item!
In the case of multi-select with multiple top-level groups we advice not to set any redirects at all as a user can become member of multiple usergroups thus redirected multiple ways ending in an infinite loop.
