'summernote' => [

            //Set to false if you want to disable this extension
            'enable' => true,

            // Editor configuration
            'config' => [
                'height' => 300,
                'disableResizeEditor' => true,
                'addclass'=> [
                    'debug' => false,
                    'classTags' => [['title' =>"Button", 'value'=>"btn btn-success"],"jumbotron", "lead","img-rounded","img-circle", "img-responsive","btn", "btn btn-success","btn btn-danger","text-muted", "text-primary", "text-warning", "text-danger", "text-success", "table-bordered", "table-responsive", "alert", "alert alert-success", "alert alert-info", "alert alert-warning", "alert alert-danger", "visible-sm", "hidden-xs", "hidden-md", "hidden-lg", "hidden-print"]],
                'toolbar ' => [
                    // [groupName, [list of button]]
                    ['img', ['picture']],
                    ['style', ['style', 'addclass', 'clear']],
                    ['fontstyle', ['bold', 'italic', 'ul', 'ol', 'link', 'paragraph']],
                    ['fontstyleextra', ['strikethrough', 'underline', 'hr', 'color', 'superscript', 'subscript']],
                    ['extra', ['video', 'table', 'height']],
                    ['misc', ['undo', 'redo', 'codeview', 'help']]
                ]
            ],

and then i add the custom js file
summernote-ext-addclass.js

protected static $js = [
        'vendor/laravel-admin-ext/summernote/dist/summernote.min.js',
        'vendor/laravel-admin-ext/summernote/dist/summernote-ext-addclass.js',
    ];

tested new extension field that increment this js but not working,so i have added it direct into vendor/laravel-admin-ext/..

i have all files in view, config in javascript is right, but not working :\ some help or information how to do?
