I have one more question. When I do have category/tag-list item with hierarcial tags, is there a way to filter it with only parents ID so the children are displaying? I need to have it like that, if someone ads new children to the parent tag, the child will be automatically in the menu. Should I modify the theme code to make this possible?
I made my tag list hierarcial with this snippet if it does matter:
`function wd_hierarchical_tags_register() {
// Maintain the built-in rewrite functionality of WordPress tags
global $wp_rewrite;
$rewrite = array(
'hierarchical' => false, // Maintains tag permalink structure
'slug' => get_option('tag_base') ? get_option('tag_base') : 'tag',
'with_front' => ! get_option('tag_base') || $wp_rewrite->using_index_permalinks(),
'ep_mask' => EP_TAGS,
);
// Redefine tag labels (or leave them the same)
$labels = array(
'name' => _x( 'Tags', 'Taxonomy General Name', 'hierarchical_tags' ),
'singular_name' => _x( 'Tag', 'Taxonomy Singular Name', 'hierarchical_tags' ),
'menu_name' => __( 'Hierarkiset tagit', 'hierarchical_tags' ),
'all_items' => __( 'All Tags', 'hierarchical_tags' ),
'parent_item' => __( 'Parent Tag', 'hierarchical_tags' ),
'parent_item_colon' => __( 'Parent Tag:', 'hierarchical_tags' ),
'new_item_name' => __( 'New Tag Name', 'hierarchical_tags' ),
'add_new_item' => __( 'Add New Tag', 'hierarchical_tags' ),
'edit_item' => __( 'Edit Tag', 'hierarchical_tags' ),
'update_item' => __( 'Update Tag', 'hierarchical_tags' ),
'view_item' => __( 'View Tag', 'hierarchical_tags' ),
'separate_items_with_commas' => __( 'Separate tags with commas', 'hierarchical_tags' ),
'add_or_remove_items' => __( 'Add or remove tags', 'hierarchical_tags' ),
'choose_from_most_used' => __( 'Choose from the most used', 'hierarchical_tags' ),
'popular_items' => __( 'Popular Tags', 'hierarchical_tags' ),
'search_items' => __( 'Search Tags', 'hierarchical_tags' ),
'not_found' => __( 'Not Found', 'hierarchical_tags' ),
);
// Override structure of built-in WordPress tags
register_taxonomy( 'post_tag', 'post', array(
'hierarchical' => true, // Was false, now set to true
'query_var' => 'tag',
'labels' => $labels,
'rewrite' => $rewrite,
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'_builtin' => true,
) );
}
add_action('init', 'wd_hierarchical_tags_register');`
