This template has support for 16 module positions. All module positions are collapsible. If no modules are published on some module positions, those module positions will automatically collapse.
Sparky framework allows you to add more module positions (if you need them) easily with user-friendly drag and drop technology. To check this, open template parameters and go to the Layout Designer tab.
The image that you can see on this page represents a "map" of all default module positions of Hot Rain template.
