/**
 * HiddenItems track a value but have no visible appearance and do not take up space in the form layout.  When using
 * Smart GWT databinding it is usually not necessary to use a HiddenItem, since the DynamicForm will track values for which
 * no actual form control exists, and will submit these 'extra' values when {@link
 * com.smartgwt.client.widgets.form.DynamicForm#saveData DynamicForm.saveData} is called.  HiddenItems only apply to forms
 * that are submitted like ordinary HTML forms, via the {@link com.smartgwt.client.widgets.form.DynamicForm#submitForm
 * DynamicForm.submitForm} method.
