I removed the categories column from "All posts" page by applying this code.

add_filter("manage_edit-post_columns", "my_post_edit_columns");
function my_post_edit_columns($columns){
  return $columns;

This code removed categories column. But still i see the categories filter in the top. Is there a way to remove it other than using CSS to hide it?

    That's because there is no relation between the categories column and the filter. You should look for another hook/filter with which you can remove the filter on top.

I tested this and it works for removing the categories dropdown on the All Posts page:

add_action( 'load-edit.php', 'no_category_dropdown' );
function no_category_dropdown() {
    add_filter( 'wp_dropdown_cats', '__return_false' );

-- below: old answer when I misunderstood the question --

The code you posted works just fine for me. But here's an alternative you might try:

add_filter("manage_posts_columns", "my_post_edit_columns" );
function my_post_edit_columns($columns){
    return $columns;

This will also impact other post types that have a 'categories' column.

  • It's not about the column, but the filter on top of the table (as written in the question).

  • Ah, I understand now. I was thinking of the screen options checkbox. Dec 31 '11 at 21:49
  • Yep. I want to remove that categories filter. I searched for hooks in this site but couldn't find anything. :( Dec 31 '11 at 21:56
  • Edited my answer and added new code now that I understand the question. Sorry for my confusion! :) Dec 31 '11 at 22:22

    Remove bulk action with: add_filter( 'bulk_actions-' . 'edit-post', '__return_empty_array' ); Not sure about date, I'm looking though. Dec 31 '11 at 22:49

I think the select elements are passed through the wp_dropdown_cats filter. So you should be able to add a filter to that which returns a blank string.

  • Can you give me some sample code? I'll try it Dec 31 '11 at 22:13
  • add_filter( 'wp_dropdown_cats', 'remove_dropdown_cats' ); function remove_dropdown_cats(){ return ''; } edit: go with Kailey's code, attatching it all to the load-edit.php action is a good idea. Dec 31 '11 at 22:23
  • Is it possible to apply code for "date" and "bulk actions" filter too? Dec 31 '11 at 22:45

Here you go

add_filter('wp_dropdown_cats', '__return_false');

Here is the original wp_dropdown_cats function, this filter will return default post categories

  • Please edit your answer, and add an explanation: why could that solve the problem?

  • If this is just a filter for the dropdown's HTML I'd expect you'd want return empty string not false?
