Create a WordPress menu (up to three levels) with the WP appearances built-in menu builder and convert it to a nice responsive dropdown using template tags.

Adds a very simple Colorbox to your linked images. This plugin is intended as an easy to use alternative to other lightbox / Colorbox 
alternatives. Unlike most other plugins with similar functionality, this one does not have any settings or requirements whatsoever, 
simple install, activate and yer done 🙂
