Custom widgets
JMobile has a large widget library which includes predefined dynamic widgets (buttons, lights, gauges, switches, trends, recipes, and dialog items), as well as static images (shapes, pipes, tanks, motors).
You can drag and drop an object from the gallery to the page, and then size, move, rotate or transform it. All widgets in the gallery are vector based, so they do not loose definition when resized.
You can, however, modify any of the pre-defined widgets to create your own custom widget. Custom widgets can be made up of several elements only including the properties needed to their purpose.
