添加菜單和文字按管理面板子菜單 - >試試這個

function jmenu_plugin_top_menu(){ 
    add_menu_page('My Plugin', 'My Plugin', 'manage_options', __FILE__, 'jmenu_render_plugin_page', plugins_url('/img/icon.png',__DIR__)); 
    add_submenu_page(__FILE__, 'Custom', 'Custom', 'manage_options', __FILE__.'/custom', 'jmenu_render_custom_page'); 
    add_submenu_page(__FILE__, 'About', 'About', 'manage_options', __FILE__.'/about', 'jmenu_render_about_page'); 
} 
function jmenu_render_plugin_page(){ 
    ?> 
    <div class='wrap'> 
    <h2>plugin page</h2> 
    </div> 
    <?php 
} 
function jmenu_render_custom_page(){ 
    ?> 
    <div class='wrap'> 
    <h2>my sub page</h2> 
    </div> 
    <?php 
} 
function jmenu_render_about_page(){ 
    ?> 
    <div class='wrap'> 
    <h2>About my plugin page</h2> 
    </div> 
    <?php 
} 

add_action('admin_menu','jmenu_plugin_top_menu');
