            'template' => "{label}\n<div class=\"col-lg-5\">{input}</div>\n<div class=\"col-lg-3\">{error}</div>", 
　　　　　　　　//修改顯示內容默認為{label}\n{input}\n{hint}\n{error}  \n是html代碼顯示時的換行

            'labelOptions' => ['class' => 'col-lg-2 control-label'],  //修改label的樣式
        ],
    ]); ?>

<?= $form->field($model, 'img_path',[  
            'template' => "{label}\n<div class=\"col-lg-3\">{input}</div>\n<div class=\"col-lg-2\"><label for=\"uploadImg\" class=\"btn btn-default forfocus1\" onclick=\"changeImg(1,'forfocus');\">選擇圖片<img src=\"\"></label></div>\n{error}",  
            'labelOptions' => ['class' => 'col-lg-2 control-label'],
        ])->textInput(['maxlength' => 255,'placeholder'=>'專題圖片','readonly'=>true])->label('專題名稱')->hint('錯誤提示信息') ?>
