This is a forum to suggest new features for mojoPortal.
Can you add the DynamicDisplayLevels property to the SiteMenu Class? I just answered a post for someone requesting to be able to only show menu items that are in the 1st and 2nd levels of the menu in a dropdown. I showed them how to hide the extra items using CSS but I think it would be cleaner to not have them show up at all in the first place. In case you want to see the post: http://www.mojoportal.com/Forums/Thread.aspx?thread=5109&mid=34&pageid=5&ItemID=4&pagenumber=1.
I have exposed this property, it will be available in the next release.
