充分利用fragment標籤，劃分不同條件下的fragment。
html文件如下：

super(id, markupId, markupProvider);

add(pwd);
}
}
private class PwdFragment extends Fragment {

pwdConfirm = new PasswordTextField("confirPwd", new PropertyModel(UserAddPage.this, "confirPwd"));
pwd.setLabel(Model.of("'密碼'"));
add(pwd.setOutputMarkupId(true).add(new ValidationStyleBehavior()));
pwdConfirm.setLabel(Model.of("'確認密碼'"));
add(pwdConfirm).setOutputMarkupId(true);
}
}顯示條件的代碼如下：
if(isAdd){
userForm.add(new PwdFragment("pwdContainer","pwdFragment",UserAddPage.this));
//密碼相同的校驗
EqualPasswordInputValidator equalPasswordInputValidator = new EqualPasswordInputValidator(pwd, pwdConfirm);
userForm.add(equalPasswordInputValidator);
}
else{
userForm.add(new HIddenFragment("pwdContainer","hiddenFragment",UserAddPage.this));
}
