The multiple tabs thing is there by default, no additional input required when making the template itself. To use it, you have to do this on a page you want the infobox to show up on: And fyi, you don't need break tags. If you need help with CSS or some specifics that you can't do in the infobox builder, you might want to look at Help:Infoboxes, Help:Infoboxes/CSS and Help:Infoboxes/Tags (these only apply when you edit the template in source mode).
