Troubleshooting navigation layout problems.
I changed the direction of the navigation in my templates or HTML preferences, but nothing changed. What gives?
A few possibilities:
You didn't rebuild pages after making the change.
The change will take effect only after you rebuild the site's pages.
You changed the default navigation direction (to "horizontal," for example) in the site's HTML preferences, but the widget tag in the template specifies another direction ("vertical").
The template can override the default navigation direction by setting the "direction" attribute in the widget tag:
<%navigation direction="vertical"%>
Check to make sure that the template is not overriding your preference.
Your current template theme may be built to accommodate only one direction.
The "Cup o' Joe" theme, for example is designed to use vertical navigation, and its layout styles contain the navigation to a very narrow column. If you change the navigation to horizontal in that context, there's not enough room for the horizontal layout to stretch its legs, and it wraps. The result looks very much like a vertical navigation.
The solution in this case is either to alter the theme template or style sheet to make room for the new layout, or to use a different theme.
