Thanks very much for your help. I have finished it.
I know it is a very simple question. But if any other new people have the
same question, just email me.

You need to give form components like DropDownChoice and TextField an
IModel into which the submitted value will be placed. You did this with a
PropertyModel for your DropDownChoice. You need to do similar for the
TextField.
Good luck, I hope you enjoy Wicket!

I am totally new in wicket, can anyone help me?
Now my code is:
//dropdownbox
add(new FeedbackPanel("dropdownfeedback"));
DropDownChoice<String> listSites = new DropDownChoice<String>(
"sites", new PropertyModel<String>(this, "selected"),
SEARCH_ENGINES);
Form<?> dropdownform = new Form<Void>("dropdownform") {
@Override
protected void onSubmit() {
info("You select : " + selected);
}
};
//add name text
TextField<String> Name = new TextField<String>("Name");
Name.setRequired(true);
dropdownform.add(Name);
ComponentFeedbackPanel fbName = new
ComponentFeedbackPanel("fbName", Name);
dropdownform.add(fbName);
//add Age text
TextField<String> Age = new TextField<String>("Age");
Age.setRequired(true);
dropdownform.add(Age);
ComponentFeedbackPanel fbAge = new ComponentFeedbackPanel("fbAge",
Age);
dropdownform.add(fbAge);
add(dropdownform);
dropdownform.add(listSites);
It get a "Attempt to set model object on null model of component:
dropdownform:Name"
