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'; })
