使用单选按钮创建自定义分类法

Question

我已通过以下代码创建了自定义分类法。但是我需要分类法是一个单选按钮，而不是复选框。我给用户的目标是一次可以选择一个分类法。

//hook into the init action and call create_book_taxonomies when it fires
add_action( 'init', 'create_type_player_taxonomy', 0 );
 
//create a custom taxonomy name it Type for your posts
 
function create_type_player_taxonomy() {
 
// Add new taxonomy, make it hierarchical like categories
//first do the translations part for GUI
 
  $labels = array(
    'name' => _x( 'Types', 'taxonomy general name' ),
    'singular_name' => _x( 'Type', 'taxonomy singular name' ),
    'search_items' =>  __( 'Search Type' ),
    'all_items' => __( 'All Type' ),
    'parent_item' => __( 'Parent Type' ),
    'parent_item_colon' => __( 'Parent Type:' ),
    'edit_item' => __( 'Edit Type' ), 
    'update_item' => __( 'Update Type' ),
    'add_new_item' => __( 'Add New Type' ),
    'new_item_name' => __( 'New Type Name' ),
    'menu_name' => __( 'Type' ),
  );    
 
// Now register the taxonomy
 
  register_taxonomy('Type',array('players'), array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'show_admin_column' => true,
    'query_var' => true,
    'rewrite' => array( 'slug' => 'type' ),
  ));
 
}

有没有办法通过单选按钮获取自定义分类法。
