Inspired by an existing joomla plugin named Sami Login(http://extensions.joomla.org/extensions/access-a-security/authentication/15958), this plugin is far more flexible and gives maximum options to customize from the plugin setting page as you need.
Basically to make a vertical login module you need to place a login module in that position which is a complex task for any normal people and even for web developers. So we made this simple and more flexible. From admin panel module manager you can collect login module id and put that module id in the plugin setting and after you activate the plugin you get such vertical login module. So same way you can use more ids with comma separated to place more modules in same place.
And even you can use module position name to load multiple modules in that position as vertical fixed position.
