The “WP Glossary” plugin helps you to create your own glossary of terms for Encyclopedia / Lexicon / Knowledge Base / Wiki / Dictionary in your website. This plugin works based on a custom post type and so you have a full editor at your disposal. Want to use already existing post type? Worry not, you are still on the correct page. This plugin allows you to choose the existing post type over plugin’s default one.
