This tutorial explains how you can add subtitles to module headers like you can see on the image to the right.

Creating Subtitles

A subtitle can be added to a module title by simply placing your subtitle text behind two "|" (pipe) characters.

For menu items, navigate to Menus->Menu Manager. Then, create a new menu item or edit an old one. Place two "|" (pipe) characters behind the titles caption and enter a text for the subline.

For modules, navigate to Extensions->Module Manager and add the subtitle text behind two "|" characters in the title property.
