title: Is there a way to remove all the contents in vBox in JavaFx?
body: <p>I'm trying to do the a Javafx project. And I have some problem with it.
  I have a list of text (labels) placed inside the vBox. Is there a way to remove all the text in the vBox? For example, when I click a button "Remove", everything inside the vBox will be disappeared. 
  Is it possible to do that? </p>
