To run the hook, copy the example below.

$dropdown_args = apply_filters( 'taxonomy_parent_dropdown_args', $dropdown_args, $taxonomy, $edit ); 
                         
if ( !empty( $dropdown_args ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the taxonomy_parent_dropdown_args callback 
function filter_taxonomy_parent_dropdown_args( $dropdown_args, $taxonomy, $edit ) { 
    // make filter magic happen here... 
    return $dropdown_args; 
}; 
         
// add the filter 
add_filter( 'taxonomy_parent_dropdown_args', 'filter_taxonomy_parent_dropdown_args', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'taxonomy_parent_dropdown_args', 'filter_taxonomy_parent_dropdown_args', 10, 3 );
