Bootstrap Tree菜单 - 使用数据提交扩展相关子菜单

Question

我使用带有strut 2的bootstrap treeview菜单。有很多子菜单。我想扩展相关的子菜单，而其他子菜单随着数据的提交而崩溃。现在我的树将到达第一个状态提交去了。

<div class="" id="navigation">
<div id="sidetree">
    <ul class="treeview" id="tree">
        <li class="expandable item1"><div><s:text name="menu.text.lAConfiguration"/><span class="arrow"></span></div>
            <ul style="display: none;">
                <li class="expandable item1"><div><s:text name="menu.text.lACustomizationRelated"/><span class="arrow"></span></div>
                    <ul style="display: none;">
                        <%--<a href="<s:url action="masterTheme"/>"><li><s:text name="link.menu.text.theme"></s:text></li></a>--%>
                        <a href="<s:url action="mainThemeUploadBanner"/>"><li><s:text name="link.menu.text.banner.upload"/></li></a>
                        <a href="<s:url action="laConfiguration"/>"><li><s:text name="link.localization.la.configuration"/></li></a>
                        <a href="<s:url action="laGroupWiseConfiguration"/>"><li><s:text name="link.la.group.wise.configuration"/></li></a>
                        <a href="<s:url action="createCommitteeMember"/>"><li><s:text name="link.menu.text.create.committee.member"/></li></a>
                        <a href="<s:url action="appealReasonRegistration"/>"><li><s:text name="link.menu.text.create.appealReason"/></li></a>
                        <a href="<s:url action="adjustmentReasonRegistration"/>"><li><s:text name="link.menu.text.create.AdjustmentReason"/></li></a>
                    </ul>
                </li>
            </ul>
        </li>
    </ul>
</div>
