With the powerful Sun Framework, module styles in JSN templates, starting from JSN Metro 2, will no longer be limited in a fixed number of boxed designs. For module styling, it's totally up to users to decide the styling properties of the modules. Take a look around to see how module styles are applied.
Module styles are configured inside Style tab (Style --> Module). You no longer need to remember the name of the module style or go through the document to find out a style name, as it can be selected within the module.
