Thanks for the advice. Yes, I have posted a question in another forum, however there were no answers as you have indicated. Sorry for not reading forum rules.
I have checked Pagination and Titled Pane. I do not like to have tabs or numbers to refer to another page. I will create a button named extra; then when I press that button>> Stage, Scene will be changed that "extra" page uses. Then, if there's a button "BACK to homepage", it will direct to main page of my application.
Does not JavaFX have a simple hyperlink command like "Back" or "Forward" buttons that we use in Web Page Explorers?
No, it doesn't. You will need to code it up yourself. What you describe resembles a simple, two-page wizard GUI. Searching the net for "JavaFX Wizard" produces some interesting results, one or more of which could be easily adapted to your purpose.
