I have a custom post type "Article" which has a custom field "issue" that is the id number of a "issue" post type that i am selecting using a simple select box.
I want to add a drop down of issues to filter the article listing found here:
edit.php?post_type=article
Is this possible? Is this sort of thing documented anywhere? I have not been able to find documentation or examples.
what hooks are there to filter lists & add selects to the filter controls?
edit.php?post_type=article
, but guessing games are not nice, please explain better and add screenshots if necessary (editing the Question, not here in the comments). But more important, what have you tried?
