Gets or sets the z-index style value for the menu.
For Internet Explorer, submenus are displayed using IFRAMEs. Using IFRAMEs keeps the menu above other form elements, such as drop-down lists. The zIndex specifies the "height" of the IFRAME relative to othjer elements on the page. The default value of 1000 should ensure that the menus are always the top-most elements on the page.
