首页同时使用侧滑栏和子页调用 出现侧滑栏在子页底下

代码如下
{{{
<div class="mui-off-canvas-wrap">
<div class="mui-inner-wrap">
<header class="mui-bar mui-bar-nav">
<a href="#offCanvas" class="mui-icon mui-icon-bars mui-pull-left"></a>
<h1 class="mui-title">广东文网</h1>

    </header>  
    <aside id="offCanvas" class="mui-off-canvas-left">  
        <button id="offCanvasHide" class="mui-btn mui-btn-primary mui-btn-block">  
            关闭侧滑菜单(js call)  
        </button>  
        <ul class="mui-table-view mui-table-view-chevron mui-table-view-inverted">  
            <li class="mui-table-view-cell">  
                <a class="mui-navigate-right">  
                    Item 1  
                </a>

                </a>  
            </li>  
        </ul>  
    </aside>  
    <script>  
    mui.init({  
            swipeBack : false,  
            subpages : [{  
                id : 'list',

                    bounce :'vertical'  
                    //scrollIndicator : "none"  
                }  
            }]  
        });  
        </script>  
    <!-- off-canvas backdrop -->  
    <div class="mui-off-canvas-backdrop"></div>

</div>
<script>
