I've dragged a navigation bar from the Design Gallery onto a web page. Digging into its structure, I see that it consists of three buttons — grouped and soft-grouped text and graphic elements on both the mouse-over and mouse-off layers. Right-mouse clicking allows me to edit the properties of the navigation bar (add buttons & sub-buttons, change buttons spacing & orientation, etc.)
Is it possible to turn my own custom button set into such a navigation bar, complete with a Properties dialog? Essentially, I'd like to lasso-select a set of custom buttons, then do Arrange | Create Navigation Bar.
