How to make link categories showup from in navigation menu?

I am using WordPress working on my new fashion designer’s blog. There are some links I would like to use as resource, but I don’t want them to show up at the side bar as WordPress links. Is there any way to add links to navigation menu?

We can easily create links and link categories with wordpress (daseboard - links - link categories). The question is How to have the list of links I add in certain link categories to show up in a page from the default navigation menu. So I don’t need to manually add the links to each sites when I want to create a resource page?

Hope this question making sense and thank you for your help.
