The document describes how the author created a navigation bar with buttons that have pop-up menus. They started by making a basic button shape and converting it to a button. Then they copied and renamed the button, aligned multiple buttons into a line, and added their logo. Next, they selected a button and added a pop-up menu by typing text for categories, choosing colors, text size, and highlight color. Finally, they set the pop-up menu position and tested the navigation bar in a browser.
