So assuming wp_list_pages is being used to display the nav bar you can add navigation to another URL. Grab the Redirectify plugin, create the Page called ‘whatever you want’, save that Page. Then edit that Page and add a Custom Field with a Key of ‘redirect’ and a Value of the url.
I have created a few pages using add pages but they do not appear on my blog http://theinvisiblementor. Am I missing something? Is there another step for me to take? Can anyone help? I am using the Kubrick theme. Is there a widget to create a nav bar?
