Modifying a Navigation Bar

No matter how often you think that you've got it just right when you first create your navigation, something's going to come along and make you change it. Some changes will be to the navigation bar itself, and some changes will be for only the images in the bar. How they're each changed differs slightly.

To modify a navigation bar:

1.	Select the navigation bar in the document.
2.	Select Modify > Navigation Bar. The Modify Navigation Bar dialog opens ( Figure 12.14 ). Figure 12.14. Some of the choices from Figure 12.13 are no longer available when you use the Modify Navigation Bar dialog.
3.	Make your changes as needed. This dialog's parameters are just like those in the original Insert Navigation Bar dialog.

To modify images in a navigation bar:

1.

Select one of the image elements in your navigation bar and double-click one of the Set Nav Bar Image actions in the Behaviors panel ( Figure 12.15 ). Figure 12.15. Double-click any behavior in the Behaviors panel to edit it. Alternatively, select it and press Return (Enter) to edit.

2.

The Set Nav Bar Image dialog opens ( Figure 12.16 ). This dialog looks similar to the Insert Navigation Bar dialog, but there are some major differences. You're only dealing with a single object from the nav bar, and you have tabs for basic and advanced modifications. Figure 12.16. The Basic tab of Set Nav Bar Image dialog deals with just the specific button. On the Basic tab, you can modify any of the parameters for Element name , image URLs, Alternate text, and the URL for the page to open . The Options let you set the image to be in the Down state initially. With the Advanced tab ( Figure 12.17 ), use nav bar image actions to swap additional images elsewhere on the page with "Also set image." Figure 12.17. The Advanced tab has options to change other images besides just the selected button. For example, an image of an entre might appear somewhere on the page when the FOOD button is in the Over state, or an image of a wine bottle might appear somewhere on the page when the WINE button is in the Over state. This type of fancy footworkcalled a disjoint rollover in Dreamweaverallows you to have multiple images that change due to a single event.

Tip

• A default opening image must be in place in the document before you can use the Advanced tab in the Set Nav Bar Image dialog to create a swap image behavior.
