Page Siblings

Ever had to manage a WP install with many pages and subpages? This plugin does nothing more than adding a metabox to every post type that is hierarchical (that is pages and any other custom post type!) with a list of all page siblings, starting with the parent, so you can have:

News
|— History
|— Our Staff
|—— Employment Opportunities
|— Our Company

Bonus: when you’re listing posts on admin pages, you can also choose to display only parents.

API

You can choose to disable some (or all!) functionality by using filters. These filters are as following:

Disable page siblings metabox completely:

add_filter('iamntz/page-siblings/add-page-metabox', '__return_false')

For my-custom-post-type

add_filter("iamntz/page-siblings/add-page-metabox/post-type=my-custom-post-type", '__return_false')

Disable the dropdown that will allow you to filter page parents or page parents & children

add_filter('iamntz/page-siblings/add-hierarchy-column-filter', '__return_false')

For my-custom-post-type:

add_filter('iamntz/page-siblings/add-hierarchy-column-filter/post-type=my-custom-post-type', '__return_false')

Set the default value for the dropdown:

add_filter('iamntz/page-siblings/add-hierarchy-column-filter', function() { return 'parents_only'; })

For my-custom-post-type:

// The allowed values are `all` and `parents_only`.
add_filter('iamntz/page-siblings/hierarchy-column-filter-default/post-type=my-custom-post-type', function() { return 'parents_only'; })

1. Upload the page-siblings folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Done. You will see a box with page siblings when you edit a page
