FREETaxonomies UI

The Dynamic Taxonomies module allows you to register and manage custom taxonomies from your WordPress admin, in Tools > Taxonomies menu.

All native taxonomies settings can be set within the UI. ACF Extended also adds more advanced settings allowing to manage posts per page, order etc…

Dynamic Taxonomy

A function name that will be called when the count of an associated $object_type, such as post, is updated

Provide a callback function name for the meta box display.

Defaults to the categories meta box for hierarchical taxonomies and the tags meta box for non-hierarchical taxonomies. No meta box is shown if set to false.

Whether this taxonomy should remember the order in which terms are added to objects

Whether to generate a default UI for managing this post type in the admin

Advanced Settings

The module comes with additional settings that allows an advanced control over taxonomies.

Front: Single Posts per pageSet posts per page
Front: Single Order/OrderbySet order/orderby setting
Front: Single TemplateSet custom template. Example: my-taxonomy-single.php
Admin: List Posts Per PageSet posts per page
Admin: List Order/Order bySet order/orderby setting

Export/Import Taxonomies

It is possible to export and import Taxonomies in a Json file using the ACF > Tools menu. Taxonomies can also be exported in PHP format, to manually register them in the functions.php file. Those tools are also available directly within the Dynamic Taxonomies UI.

Register Taxonomies in PHP

Taxonomies can be registered using register_taxonomy() and benefit from ACF Extended advanced settings like “Front: Single Posts Per Page” or “Admin: List Order/Order by”. See documentation. Usage example:

add_action('init', 'my_init');
function my_init(){
    register_taxonomy('my-taxonomy', array('my-post-type'), array(

        'label' => 'My Taxonomy',
        // Front
        'acfe_single_template' => 'my-taxonomy-single.php',
        'acfe_single_ppp' => 999,
        'acfe_single_orderby' => 'title',
        'acfe_single_order' => 'ASC',
        // Admin
        'acfe_admin_ppp' => 999,
        'acfe_admin_orderby' => 'title',
        'acfe_admin_order' => 'ASC'

Existing Taxonomies

Advanced settings can be used in already existing taxonomies using the register_taxonomy_args hook. See documentation. Usage example:

add_filter('register_taxonomy_args', 'my_taxonomy_args', 10, 3);
function my_taxonomy_args($args, $taxonomy, $post_types){
    // Target "my-taxonomy"
    if($taxonomy !== 'my-taxonomy')
        return $args;
    // Set Front: Archive Posts Per Page
    $args['acfe_single_ppp'] = 999;
    // Return
    return $args;

Hide the module

ACF Extended use the native ACF setting show_admin to determine if the module menu should be displayed or not. You can read more about that setting on the ACF article How to hide ACF menu from clients. Usage example:

add_filter('acf/settings/show_admin', '__return_false');

Disable the module

The Taxonomies module is enabled by default. It can be enabled and disabled in the Settings UIPRO, or with the following code:

// Using acf/init
add_action('acf/init', 'my_acfe_modules');
function my_acfe_modules(){

    // Disable Taxonomies
    acf_update_setting('acfe/modules/taxonomies', false);

// Or using acfe/init
add_action('acfe/init', 'my_acfe_modules');
function my_acfe_modules(){
    // Disable Taxonomies
    acfe_update_setting('modules/taxonomies', false);
