Menu design

The menu item design properties are available in three alternatives:

•	standard design

•	mouse-over design - style used when you mouse-over the menu item

•	highlighted design - style of the selected document

These values override the settings of the menu control (web part) and the CSS styles defined in the CSS stylesheet.

Please note: some of the following properties may not be applied to the menu control depending on the menu control you are using.

Menu item style	Style definition of the menu item. Values can be entered the same way as when defining a CSS class in a stylesheet. Sample value: color: orange; font-size: 140%
Menu item CSS class	CSS class defined in the website's stylesheet. Sample value: h1
Menu item left image	Image that will be displayed next to the menu caption on the left side. Sample values as below.
Menu item image	Image that will be displayed in the menu instead of the menu caption. You can enter either an absolute URL or a relative path in the content tree. Sample values: http://www.domain.com/image.gif ~/Images-(1)/icon.aspx
Menu item right image	Image that will be displayed next to the menu caption on the right side. Sample values as above.
