This example demonstrates how to build a simple dynamic form. Main steps:

  • Create model instance: DynaFormModel model = new DynaFormModel();
  • Add row to regular grid: DynaFormRow row = model.createRegularRow();
  • Add label: DynaFormLabel label = row.addLabel(value, colspan, rowspan);
  • Add editable control: DynaFormControl control = row.addControl(data, type, colspan, rowspan);
  • Set relationship between label and control (optional): label.setForControl(control);
Repeat four last steps as many times as needed. The main component tag is pe:dynaForm. Child tag pe:dynaFormControl matches created in Java controls by type attribute. This is usually a "one to many" relation.

You also see that one of important features is a buil-in support for labels. DynaForm renders labels automatically - no need to write p:outputLabel. But of course h:outputText can be used as a quite normal tag inside pe:dynaFormControl with a proper type as well.
