Webdesigner Pro X dropdown pages in navbar

Hi Talkgraphics friends, I'm using Webdesigner Pro X, and I would like to add dropdown pages to my navbar.
How do I do this, and where are the pages when created?

I've searched, and cannot find how to do this, can someone help me, or point me to where I can get info?

I realize this is elementary, but, I'm stumped (on this and most everything else).

Thanks for any help, Robertg.

You have to create the new pages first, then add them to your navbar via the Arrange>>Create Navigation bar dialogue

Sledger, thank you, I appreciate your help.

Best regards, Robertg
