Tabs widget tabs as text input

How I can convert the tabs in to free-form text-input.

I am able to insert the text area field in tabs as in the example code, but I want the whole tab to behave like a text page. I have seen this in other applications. How I can achieve this?

<?php


$tab2 = "This is the sample content of tab2";


echo Tabs::widget([

    'items' => [

        [

            'label' => 'One',

            'content' => $form->field($model, 'sample_text')->textArea(['label'=>false]),

            'active' => true

        ],

        [

            'label' => 'Two',

            'content' => $tab2,

            //'headerOptions' => [...],

            'options' => ['id' => 'myveryownID'],

        ],

        

    ],

]);

?>

Thanks.
