The jQuery Mobile framework uses HTML5 data- attributes to allow for markup-based initialization and configuration of widgets. These attributes are completely optional; calling plugins manually and passing options directly is also supported. To avoid naming conflicts with other plugins or frameworks that also use data- attributes, set a custom namespace by modifying the ns global option.
