        <a class="btn btn-default pull-right" data-remote="<?= Url::toRoute(['create', '_wicket' => 'yes']) ?>"

           data-toggle="modal" data-target="#myModal" role="button">添加地区</a>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

    <div class="modal-dialog" role="document">

        <div class="modal-content">

            <div class="progress" style="margin:0;"><div class="progress-bar progress-bar-info progress-bar-striped active" role="progressbar" 
            aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 1%"></div></div>
