[wp-hackers] Assigning Custom List Type to Custom Post Type (removing filter by post date)

[Lionel Pointet]

Tom,

One way of doing it is to "hide" that filter (with CSS) or remove it 
with JS. Indeed, you can easily add an extra class to the body with 
'admin_body_class' filter (depending on the $pagenow and $post_type 
global vars for example) to only target your CPT list.

To add one or more filters after those included by WordPress, you can 
use the 'restrict_manage_posts' action.

Unfortunately, I think that John is right on that, you cannot extend the 
list table classes for now.

Hope that helps.
Lionel
