[RESOLVED] Custom Post Types compatible
-
I liked this slider for it’s elegant simplicity, but it lacked the necessary Custom Post type integration that I needed. So I modified it.
This version:
- Is compatible with Custom Post Types
- Offers show/hide for Titles
- Offers show/hide for Slider Navigation
Enjoy!
NOTE: This code replaces the code inside news-scroller.php
