This plugin adds classes or IDs (your choice) to the <code>LI</code> tags generated by WordPress’ <code>wp_list_pages()</code> and <code>wp_nav_menu()</code> functions.
I found it very frustrating to style the output of these menus without having access to these attributes. This plugin allows you to style the output of <code>wp_list_pages()</code> and <code>wp_nav_menu()</code> with CSS.
The class name or ID is derived from the URL of the page.
For example,
<ul>
<li><code>/about/</code> could have the class <code>about</code>. </li>
<li><code>/about/faq/</code> could have the class <code>about_faq</code>.</li>
</ul>
If a page does not have a URL (e.g. your front page) the plugin will set the <code>class</code> or <code>id</code> (depending on what you selected) to <code>frontpage</code>, adding whatever prefix you requested.
For example,
<ul>
<li><code>/</code> could have the class <code>pg_frontpage</code>. </li>
</ul>
Existing classes (e.g. <code>page_item</code> or <code>current</code>) are left untouched.
<h4>Sample output</h4>
<pre><code><li id="nav-a-new-page" class="first page_item page-item-4"><a href="http://example.com/a-new-page/" title="A new page">A new page</a></li>
<li id="nav-about" class="page_item page-item-2"><a href="http://example.com/about/" title="About">About</a></li>
<li id="nav-another-new-page" class="last page_item page-item-6"><a href="http://example.com/another-new-page/" title="Another new page">Another new page</a></li>
</code></pre>
<h4>Configuration</h4>
Using the <code>Classy wp_list_pages</code> tab in the options panel you can choose whether you want to use IDs or classes, set the token separator and add an optional token prefix.
You can also specify a class to add to the first and last items in a list.
Pretty straight forward…

This plug-in limits the classes WordPress added to navigation menus to only those desired by the Theme owner, 
adds a unique ID to each <code>li</code> and removes any empty <code>class</code> attributes.

Navigation Menu IDs & Classes

At least some aspect of this plugin seems like it should be available in WordPress core. 
I understand the rationale for menu items having menu-item-ID, but it's pretty practical for them to have the slug in there, as this plugin provides.
Suggestion for plugin feature - offer option for slug prefix.
Like if I have a menu item "updates" I may use the class "updates" elsewhere, but class "menu-item-updates" would target the menu-item for sure. Of course I can currently use double selectors.



1 for inclusion in core

To reduce the extraneous WordPress classes and add unique IDs to navigation menus.
