Summary and details
Features Posts is a custom function for this World of Warcraft WordPress theme (applies to both V2 and V3)
Featured Posts appear on custom front page templates such as Excerpts and Full Posts.
To create Featured Posts, simply assign “featured” category to any post in your WordPress blog and set featured image for it.
The code will display the post in the slider automatically, nothing else needs to be done.
One detail to be aware of that Featured Posts in slider only appear there and they do not appear on front page excerpt row. This prevents duplicate content on your page.
