A conditional two-level menu only shows the second level of the menu on relevant pages.
For example, if you had a menu that had a structure like so:
<ul>
<li>Home</li>
<li>About
<ul>
<li>History</li>
<li>People</li>
</ul>
</li>
<li>Contact
<ul>
<li>Mail</li>
<li>Phone</li>
<li>Email</li>
</ul>
</li>
</ul>
You would only be able to see the “History” and “People” menu items on the “About,” “History,” and “People” pages.

Two Level Conditional Menu

This plugin converts a two-level menu to a conditional two-level menu.

This plugin adds a checkbox, “include this page in menus”, uncheck this to exclude pages from the page navigation that users see on your site.
Any issues: <a href="http://www.simonwheatley.co.uk/contact-me/" rel="nofollow ugc">contact me</a>.This plugin adds a checkbox, “include this page in menus”, which is checked by default. If you uncheck 
it, the page will not appear in any listings of pages (which includes, and is usually limited to, your 
page navigation menus).
Pages which are children of excluded pages also do not show up in menu listings. (An alert in the editing screen, 
underneath the “include” checkbox allows you to track down which ancestor page is affecting child pages 
in this way.)
<h3>Advanced Usage</h3>
It is possible to temporarily pause and resume the effect of Exclude Pages by using the new <code><?php pause_exclude_pages(); ?></code> and <code><?php resume_exclude_pages(); ?></code> templates tags. The following code will show a list of all pages in your site, even those normally hidden:
<pre><code><?php pause_exclude_pages(); ?>
<?php wp_list_pages('title_li=<h2>Pages</h2>' ); ?>
<?php resume_exclude_pages(); ?>
</code></pre>
You can also get an array the IDs of the pages which are excluded by calling the function <code>ep_get_excluded_ids();</code>, you can then use these IDs as you wish (e.g. feed them into raw MySQL queries).
Note to other plugin authors:
The plugin does not operate on wp_list_pages while the user is on an admin page, if this is an issue you can take advantage of the <code>ep_admin_bail_out</code> filter and create a filter function which returns false to allow Exclude Pages to operate in the admin area.
Another note:
If your plugins or themes don’t use the standard WordPress functions to create their menus then they won’t work. To get them to work you will need to track down the bit of code in the theme/plugin which gets the pages and change it to apply the filter “get_pages” (I cannot be responsible for any unforseen effects of the changes you make, so please test thoroughly). The change to getting pages will probably look something like this:
<pre><code>$pages = apply_filters( 'get_pages', $pages );
</code></pre>

Exclude pages is incompatible with:
