<div id="sidebar-scrollTop">
                    <ul class="nav-list">
                        <c:if test="${!empty oper}">
                            <c:forEach items="${oper}" var="funmenu">
                                <c:if
 
 test="${funmenu.mtype==0 && empty funmenu.gren}">
                                    <c:if test="${!empty funmenu.content }">
                                        <li>
                                        <ul>
