How to add valueless attribute to <form> tag

问题:

How do I add a value-ess attribute to the form tag?

I want to have:

<form data-abide >

according to: http://foundation.zurb.com/sites/docs/abide.html

I've tried

<?php $form = ActiveForm::begin(['id' => 'contact-form', 'options'=>['data-abide'=>'']]); ?>

but get output:

<form data-abide="ak8hvf-abide" >

Try this:

'options'=>['data-abide'=>true]

Reference: In the framework helper BaseHtml.php file, find ：

function  renderTagAttributes

Where :

foreach ($attributes as $name => $value) {if (is_bool($value)) { if ($value) { $html .= " $name"; } } elseif...
    ...
    elseif ($value !== null) { $html .= " $name=\"" . static::encode($value) . '"'; }
    ...

It is actually behaving as expected - turns out it is the adide.js which adds the extra security token: https://github.com/yiisoft/yii2/issues/10532#issuecomment-169952232

Thanks everyone for help!

For me, both 'data-abide'=>'' and 'data-abide'=>true works fine...

Could it be something outdated? Can you try run a composer update in your project?
