Bootstrap div溢出了JQuery模态

Question

我有一个小的前端问题。当我将Bootstrap DIV加载到JQuery Modal的主体中时，它会流入页脚而不是扩展主体。感谢。

        <div class="modal fade col-sm-4 col-sm-offset-4" id="register" role="dialogue">
            <div class="modal-dialogue">
                <div class="modal-content">
                    <div class="modal-header">
                        <h4>Register</h4>
                    </div>
                    <div class="modal-body">
                        <form action="" method="POST">
                        <div class="form-group">
                            <div class="col-sm-12">
