1、执行：composer require ichynul/iframe-tabs
2、发布：php artisan vendor:publish --tag=iframe-tabs
3、发布：php artisan admin:import iframe-tabs
4、在config/admin.php添加：
'extensions' => [
        'iframe-tabs' => [
           // Set to `false` if you want to disable this extension
            'enable' => true,
            // The controller and action of dashboard page `/admin/dashboard`
            'home_action' => App\Admin\Controllers\HomeController::class . '@index',
            // Default page tab-title
            'home_title' => 'Home',
            // Default page tab-title icon
            'home_icon' => 'fa-home',
            // Whether show icon befor titles for all tab
            'use_icon' => true,
            // dashboard css
            'tabs_css' =>'vendor/laravel-admin-ext/iframe-tabs/dashboard.css',
            // layer.js path
            'layer_path' => 'vendor/laravel-admin-ext/iframe-tabs/layer/layer.js',
            /**
             * href links do not open in tab .
             * selecter : .sidebar-menu li a,.navbar-nav>li a,.sidebar .user-panel a,.sidebar-form .dropdown-menu li a
             * if(href.indexOf(pass_urls[i]) > -1) //pass
             */
            'pass_urls' => ['/auth/logout', '/auth/lock'],
            // When login session state of a tab-page was expired , force top-level window goto login page .
            //登录超时是是否强制整体跳转到登录页面，设为false的话只在触发超时登录的页面跳转，最大程度保留已打开页面。
            'force_login_in_top' => true,
            // tabs left offset
            'tabs_left'  => 42,
            // bind click event of table actions [edit / view / create]  
            'bind_urls' => 'popup', //[ popup / new_tab / none]
            //table actions dom selecter, [view / edit / create]buttons ,and any thing has class pupop : mylink
            'bind_selecter' => 'a.grid-row-view,a.grid-row-edit,.column-__actions__ ul.dropdown-menu a,.box-header .pull-right .btn-success,.popup',
            //layer popup size
            'layer_size' => '1100px,98%',
            // if run web in `cli` mode ,for example `swoole` ,set it to true，如果是以命令行方式运行网站，如`swoole` 就设置为 true
            'web_in_cli' => false
        ]
    ],

5、在resources/lang/{zh-CN}/admin.php中添加：
'iframe_tabs' => [
    'oprations' => '页签操作',
    'refresh_current' => '刷新当前',
    'close_current' => '关闭当前',
    'close_all' => '关闭全部',
    'close_other' => '关闭其他',
    'open_in_new' => '新窗口打开',
    'open_in_pop' => '弹出窗打开',
    'scroll_left' => '滚动到最左',
    'scroll_right' => '滚动到最右',
    'scroll_current' => '滚动到当前',
    'goto_login' => '登录超时，正在跳转登录页面...'
],

注：去掉'滚动到最左'、'滚动到最右'、'滚动到当前'需要去vendor/ichynul/iframe-tabs/resources/views/ext/options.blade.php中注释html语句
