Bootstrap 导航栏中的二级菜单显示隐藏链接

问：

我在带有 C# 的 ASP.NET 应用程序中使用 Bootstrap。我有两级菜单，有些选项可供用户使用，有些选项可供管理员使用。母版页中的页面加载决定了在菜单中显示或隐藏链接的选项。它在桌面模式下工作正常，但在移动设备中，它也显示隐藏的链接，这些链接只能显示给管理员。

<ul class="navbar-nav">
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton5" runat="server" Visible="false" PostBackUrl="#">Link 01</asp:LinkButton>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton6" runat="server" Visible="false" PostBackUrl="#">Link 02</asp:LinkButton>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton4" runat="server" Visible="false" PostBackUrl="#">Link 03</asp:LinkButton>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton2" runat="server" Visible="false" PostBackUrl="#">Link 04</asp:LinkButton>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton7" runat="server" Visible="false" PostBackUrl="#">Link 05</asp:LinkButton>
    </li>
    <li class="nav-item dropdown">
    <a runat="server" class="nav-link dropdown-toggle" href="#" id="dropdown04" data-toggle="dropdown" aria-expanded="false" aria-haspopup="true" Visible="false">Link With Sub Menu</a>
      <div class="dropdown-menu" aria-labelledby="dropdown04">
        <a class="dropdown-item" href="#">Sublink 01</a>
        <a class="dropdown-item" href="#">Sublink 02</a>
        <a class="dropdown-item" href="#">SubLink 03</a>        
      </div>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton1" runat="server" Visible="true" PostBackUrl="#">Link 06</asp:LinkButton>
    </li>
    <li class="nav-item active">
        <asp:LinkButton class="nav-link" ID="LinkButton3" runat="server" Visible="False" OnClick="LinkButton3_Click">Link 07</asp:LinkButton>
    </li>                           
</ul>

背后的代码是

if (Session["PersonType"] != null && Session["PersonType"].Equals("Admin"))
{
    LinkButton1.Visible = false;
    LinkButton2.Visible = false;
    dropdown04.Visible = true;
    LinkButton3.Visible = true;
    LinkButton4.Visible = false;
    LinkButton5.Visible = true;
    LinkButton6.Visible = true;
    LinkButton7.Visible = true;
}
else
{
    LinkButton1.Visible = true;
    LinkButton2.Visible = true;
    LinkButton3.Visible = false;
    LinkButton4.Visible = true;
    LinkButton5.Visible = false;
    LinkButton6.Visible = false;
    LinkButton7.Visible = false;
    dropdown04.Visible = false;
}

即使管理员未登录，也会显示 dropdown04 菜单项。但它仅在移动模式下显示，而不在桌面模式下显示。桌面模式工作正常。问题仅在移动模式下出现。

有些人建议将 data-toggle 添加到 data-bs-toggle 并将 data-target 添加到 data-bs-target，但它并没有为我解决问题，而是停止在移动视图中展开菜单。
