All,

  Just illustrating our hack to add horizontal lines between menu items. Hope some one finds it helpful or can give a better suggestion.

1.Add to your menu.css a class

.main_dnnmenu_bar

div.hr {

width

2. Add a page/tab with title <div class="hr"/>

3. Set the above page as link to the menu item above or below as u wish(for seo)

This method gives u control of just where u wnat the line.
