title: How to create multiple javafx controllers with different fxml files?
body: <p>I've been looking at some blogs and other stackoverflow questions, and I'm not seeing a direct answer to my question. I am creating a javafx gui client and I want to have my menubar be one controller in one fxml and then i want the content area to be additional fxml files. The login screen will be one fxml, after the login screen will be the main content of the application and that will be in one fxml. How do i go about doing this? </p>
  
  <p>I just don't want to have all of my code for my login, menubar, and main content in the same file. This is an image of what i am working on:</p>
