This covers the basics of how to exclude pages from your navbar listings, but there’s only one problem (and at first I was freaking out over this): they indicate to exclude by page ID, but the newer versions of WordPress don’t use a page ID, SO, here is what you do:

1) Go to ‘Pages > Edit’
2) Mouseover the page you will be wanting to exclude from your list, and see the URL that appears (for example: http://www.kevinpajak.com/blog/wp-admin/page.php?action=edit&post=2). You notice that you will actually see the number listed as a post!
3) Grab this number for each page you need to exclude, and plop it into this code in your header/sidebar/navbar page code:

For example:
<?php wp_list_pages(‘exclude=16,18,20,22′); ?>

Voila! You should be all set (Oh, and if your wp_list_pages function happens to have additional code, you will need to make sure you include the ampersand character with it (&).

Ex:
<?php wp_list_pages(‘title_li=&exclude=96,98,100,102,104′); ?>

Last of all, there is also a plugin you might want to try, called ‘Exclude Pages’ that should take care of this for you automatically if you prefer. I haven’t tried it yet, but definitely worth a look .

Have fun WordPressers, good luck, and please feel free to share your feedback anytime! .

PS: To exclude categories from your navigation listings, follow the same procedure:

1) Take a look at your overall category list (‘Edit > Categories’),
2) This time find the CAT ID (Ex: http://www.kevinpajak.com/blog/wp-admin/categories.php?action=edit&cat_ID=3)
3) Note that number(s) and enter them in the line of code that reads, for example:
<?php wp_list_categories(‘exclude=6,8,21′); ?>

THEME FIX LIST:
1) Add ‘Edit’ link to posts/pages (for admin). Again, this is a really nice blog theme, but for some reason, the authors put in the Edit link for the Comments and not the Posts! Anyway, will get it.
2) Edit ‘Home’ link to go to KevinPajak.com, and not blog home (the title already links to Blog home page).
3) Add some additional breathing space to the feed list items.

I think that’s it for now… Rock on!
