Bulk Actions Select All

Bulk Actions: Select All adds an option to the posts and taxonomy terms overviews in the WordPress Admin to select “All Entries”. By default, WordPress only allows you to select the posts/terms on the current page.

Supported content types

The plugin works for posts, pages and custom post types. Furthermore, it supports categories, tags and custom taxonomies. At this point, it doesn’t support comments and other object types besides post types and taxonomies.
