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.

JS Morisset

If no featured image has been selected for a post, page, or custom post type, this plugin will assign the first featured image found from its parent, grand-parent, great-grand-parent, etc.
The plugin makes no permanent changes – simply deactivate the plugin to disable the automatically inherited images. 😉
<h3>Coded for Performance</h3>
This plugin uses the WordPress <code>wp_cache_get()</code> and <code>update_meta_cache()</code> functions for maximum performance and fully integrate with WordPress core functionality.

JSM Inherit Parent Featured Image

Inherit the featured image from the Post, Page, or Custom Post Type parent, grand-parent, great-grand-parent, etc.
