Most Posts and Custom posts in WordPress are supported by the WordPress Bulk Posts Editing plugin.
This means you can switch between them easily through the “Select post type” field.
All default fields are supported by this plugin and if there were any other fields, you should add them by “Meta Fields”.
Do you still have a problem?
If after reading the articles you still think have unanswered questions or need custom work for your plugin, contact iThemeland Support.
