Форма jquery-steps не отправляется

После некоторых проб и ошибок я нашел проблему. Идентификатор #wizard должен быть в теге формы:

{{ Form::model($contractor, array('url' => 'contractors/edit', 'id' => 'wizard', 'class' => 'form-horizontal', 'method' => 'PUT')) }}

Также удалите тег, хранящий id="wizard", и все заработает.

я удалил дочерний элемент div, теперь он работает нормально,

<form id="example-form" action="<?php echo getCmsUrl('add/payment'); ?>">
            <h3>Your Information</h3>

И в js-скрипте

<script type="text/javascript">
        var form = $("#example-form");
        form.validate({
