Hi. I'm new to WP and am stumbling on how to edit my header to show limited links. Basically, what I want to do from the main page is to only show header links only for pages that have no parent pages. Then when I click into one of those main page links, then I want to show the children pages.
For example, for what I have uploaded to intuiosity.com so far, I only want to show About and Overview pages in the header link. However, if I publish other (children) pages, then they show up in the header links.
Any tips would be appreciated.

not a support question
