asp.net - 带有站点地图的菜单未在所有浏览器中显示子项

Question

无法让我的菜单显示我的任何子项目。它显示有一个子项目的箭头，但是当我将鼠标悬停在上面时，它们不会弹出。是的，我确实在这里查看了其他问题。

<asp:Menu ID="Menu1" runat="server" DataSourceID="SiteMapDataSource1" StaticDisplayLevels="2" 
        Orientation="Horizontal">
    </asp:Menu>
    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />



<siteMapNode url="~/default.aspx" title="Home">
<siteMapNode url="~/organizations/organizations.aspx" title="My Organization" />
<siteMapNode url="~/locations/locations.aspx" title="Locations" >
</siteMapNode>
<siteMapNode url="~/requests/landing.aspx" title="Request" >
  <siteMapNode url="~/requests/location.aspx" title="Location" />
  <siteMapNode url="~/requests/locationmanager.aspx" title="Location Manager"  />
  <siteMapNode url="~/requests/organization.aspx" title="Organization"  />
  <siteMapNode url="~/requests/organizationmanager.aspx" title="Organization Manager"  />
</siteMapNode>
<siteMapNode url="~/admin/landing.aspx" title="Admin" >
  <siteMapNode url="~/admin/categories/manage.aspx" title="Manage Categories"  />
  <siteMapNode url="~/admin/locationtypes/manage.aspx" title="Manage Location Types" />
  <siteMapNode url="~/admin/metadatatypes/manage.aspx" title="Manage Meta Data Types" />
  <siteMapNode url="~/admin/requests/manage.aspx" title="Manage Requests" />
  <siteMapNode url="~/admin/weekdaytemplates/manage.aspx" title="Manage Week Day Templates" />
</siteMapNode>

编辑：这是我的萤火虫代码
