In the same way as we can set-up a Category Tree, I would like to be able to set a topic Tree so that I can define a hierarchy if I want. I might have sections such as Customer Service, Articles, About Us and then child pages within those. Modify the navigation menu so that topics can be included in the menu then and show the children as per the Tree. Also add a flag onto the topic "Show On Menu".
I think you can have a look on this plugin: https://www.nopcommerce.com/boards/t/25860/add-articles-news-promotions-tips-reviews-etc-to-your-website.aspx
