# [Plugin: Event] Adding sortable custom columns to admin screen

 * This plugin is currently showing the custom column event_date just fine but I’d
   like to be able to sort it on the WordPress admin back-end like the other columns
   that already exist, (Title and Date).
 * This is for the custom post type event. I thought this could be handled with 
   the add_filter for manage_custom-post-type_sortable_columns function. What am
   I missing?
