Hiding Wordpress pages

I was wondering if there is a way to hide certain pages (pages, not posts) from displaying in the header, so the only way to access them would be through a direct link?

Also, is there a way to do this with categories? As in, make it so certain categories don't show up in the category list in the sidebar? Thanks!

 

For posts:

<?php wp_list_pages('exclude=17,38' ); ?>

Code (markup):

For categories:

<?php wp_list_categories('exclude=4,7&title_li='); ?>

Code (markup):

Change the numbers after the exclude to the page/category ID you don't want links to.

 

Where do I put that?

 

I put my code,

<?php wp_list_pages('sort_column=menu_order&depth=1&title_li=&exclude=1001'); ?>

into header.php

For some reason though, it does not work like it's supposed to and the page still shows up in the nav bar! Don't know what's wrong, but based on what everyone says the code is correct.

 

Just use the plugin called Page Link Manager and you can do it with one click every single time you publish a page and also for the existing ones.

 

Thanks, that's exactly what I needed. Is there one for categories?

 

I really never used anything for categories... But this plugin should help you. http://www.ryowebsite.com/?p=46

also, there are plenty of javascript related plugins which shows dropdown categories.

But if you are thinking of showing specific categories to specific people, then check out Wp Members Plugin.
Cheerios!
