Creating new themes
I created a new theme for a vertical glow menu. The graphics should be completely compatible with a horizontal menu.
When I try to use a horizontal menu with this theme, the WA preview is vertical, the DW preview looks right, and the page has a vertical menu.
I looked at the source files in the config shared folder, and I cannot figure out how the different views are generated for the existing themes which all default to horizontal. I am afraid of overwriting my vertical theme.
How do I generate ONE theme that can be displayed vertically or horizontally like the included themes?
Also, I would like to include a feature request. I think there should be an option for adding an icon, like an arrow, WHEN there is a sub-menu and a different icon (or no icon) when there is no submenu.


It may have to do with how you are editing the menu as I'm not able to get this result with a similar set of steps. I would suggest that you create a new menu and specify it to be a horizontal menu all along the way and when you save the preset include Horizontal in the title so you know to use that one for the horizontal applications.
