问题描述
我正在开发一个允许用户浏览生产服务器上的特定文件目录的应用程序，我希望用户能够在使用网站时添加其他菜单项，以及创建一个新的菜单项还应该能够指定链接到这个新菜单项的新文件目录值。
有没有办法可以让最终用户动态添加其他项目到这个菜单并设置配置值，而没有单独的管理功能页面来创建新的菜单项？
这里是菜单的设置方式：
I am working on an application that allows users to browse particular file directories on production servers and I would like to allow the user to be able to add additional menu items whilst using the site, as well as creating a new menu item they should also be able to specify a new file directory value linked to this new menu item.
Is there a way that I can allow the end user to dynamically add additional items to this menu and set the config value without having a separate admin functionality page to create the new menu item?
Here''s how the menu is setup:
<table width="100%">
<tr>
<td colspan="3" rowspan="1" style="width: 100%; height: 30px" valign="top">
<asp:Menu ID="Menu1" runat="server" BackColor="#B5C7DE" DynamicHorizontalOffset="2"

Your menu is defined in the code. You probably don’’t want to allow user to alter code. So change your point of view: you don’’t need to allow user to add menu items, you need to define and put in place a feature that can populate the menu fully or partially in a dynamic manner. You also need to store and retrieve the data of these dynamic items somewhere: in a database for example. Please look at following article for a possible solution: Dynamically populating menu items from the database in ASP.NET[^]
