I want to create a theme for ISPconfig according to Twitter's Bootstrap
. This should not be too much work, but I can't get around how the ISPconfig themes are composed. I understand how the main.tpl.htm is the main page and how the other .tpl.htm files are the specific elements like navigation, but I would expect some kind of includes in that main.tpl.htm page that calls for the other interface elements but there aren't any.
Where is it defined where the, for example, topnav.tpl.htm should go?
