This plugin is meant to solve the problem of highlighting “parent” pages for Custom Post Types in the menu and lists of pages. It integrates with custom menu output as well as output for any functions like <code>wp_list_pages()</code> that utilize the <code>page_css_class</code> or <code>nav_menu_css_class</code> filters. When viewing a custom post type, the assigned “parent page” will be indicated with standard WordPress classes (e.g. current_page_item) in navigation menus and lists of pages.
<h4>Usage</h4>
<ol>
<li>In the admin, navigate to Settings > Custom Post Type Parents</li>
<li>For each custom post type, use the dropdown to select a “parent page”</li>
</ol>
Menus and lists of pages will now have the appropriate classes applied to the specified parent pages. Additionally, Custom Post Type Parents will apply these classes to <a href="https://wordpress.org/plugins/simple-section-navigation/" rel="ugc">Simple Section Navigation</a> widgets, if the plugin is installed.
<h4>Classes</h4>
Custom Post Type Parents applies the following classes to parent and ancestor pages (all classes are consistent with default WordPress classes and are backwards compatible).
Parent 
* current-menu-parent 
* current_page_parent 
* current-custom-post-type-parent 
* current-{post type}-parent
Ancestor 
* current-menu-ancestor 
* current_page_ancestor 
* current-custom-post-type-ancestor 
* current-{post type}-ancestor

Custom Post Type Parents

Set a "parent page" for custom post types that is indicated in menus, lists of pages, and the Simple Section Navigation widget.

IMPORTANT: This plugin is not compatible with the Mystique theme, nor is it compatible with the WordPress 3.x custom menu system (that is, menus created using the drag-and-drop menu builder under Appearance->Menus). If you want to create an unlinked parent menu item with the Mystique theme, install Mark Jaquith’s ‘Page Links To’ plugin, and put a ‘#’ (hash/pound) mark in the ‘Point to this URL:’ field to create a dummy link. For the WP3 menu builder, use a ‘Custom Link’ with a ‘#’ mark in the URL field. Refer to the documentation in the WP Codex if you need more help: https://codex.wordpress.org/Appearance_Menus_Screen#Custom_Links
When activated, this plugin unlinks parent pages (that is, pages that have child pages underneath them in a hierarchy) in page menus and lists. It affects the output of wp_list_pages and wp_page_menu, as well as all plugins and widgets that use those functions.
The plugin works by turning the parent page links into ‘dummy links’. That is, it replaces the href attribute on parent menu items with a ‘#’ (hash/pound) mark. A dummy link is just like a regular link, except that it leads back to the current page when clicked. The dummy links are given an inline style “cursor: default” to prevent the mouse pointer from turning into a hand when hovering over unlinked menu items.
<h4>Options</h4>
To configure the plugin options, go to the Settings menu in the WordPress admin panel and click on ‘Unlink Parent Pages’.
Use Dummy Links 
Turned on by default as of Unlink Parent Pages version 1.3. If you uncheck this box, the plugin will unlink the parent pages by replacing the anchor tags with span tags. In some themes, this may cause problems with CSS styling. In order to fix this, you would need to add an additional selector to any rule that targets the anchor tags (see the FAQ for more information). If you are not experienced in writing CSS selectors, then it is strongly recommended to stick with dummy links.
Unlink Current Page 
Unlink the current page, in addition to the parent pages.
Remove Link Titles 
Remove the title attribute from the links (stops the tooltip from popping up when the mouse hovers over the menu items). This doesn’t have anything to do with unlinking parent pages, but it’s something a lot of people want, so I decided to include it.
Maximum Depth 
The maximum depth setting controls how many levels in the hierarchy of pages are to be unlinked. It works exactly like the ‘depth’ option for wp_list_pages, as follows:
<ul>
<li>0 (default) Unlinks all parent pages, anywhere in the page hierarchy.</li>
<li>1 Unlinks top-level parent pages only.</li>
<li>2, 3, … Unlinks parent pages to the given depth.</li>
<li>-1 Do not unlink any pages (specify individual pages instead).</li>
</ul>
Unlink Specific Pages 
You can specify which pages you want unlinked, using a comma-separated list of page IDs (example: 3,7,31). It works exactly like the ‘exclude’ option for wp_list_pages. If you want only the specified pages to be unlinked, then set max depth to -1.
