Question

我有一个包含子菜单的菜单，我希望子菜单继承其<li>的菜单。例如admin的子菜单就像admin的宽度一样，home的子菜单与管理宽度的宽度不同，就像宽度一样home。

以下是菜单：http://jsfiddle.net/2fDQz/5/（子菜单位于home和admin）

css（虽然你可以在jsfiddle中看到它）：

Answer 1

您可以将宽度：100％提供给子菜单，它可以正常工作

<div id='personalbar'style="position:absolute; top:0%;left:0%; width:100%;">
<ul>
   <li><a href='# '><span>Home</span></a>
   <ul style="width:100%">
   <li id="Li2" runat="server"><a id="A5" href="#" runat="server"><span>bla</span></a></li>
   <li id="Li3" runat="server"><a id="A6" href="#" runat="server"><span>bli</span></a></li>
   </ul></li>
  <li id="L1"  runat="server"><a id="A1" href="../ClientSide/newsFeed/allEr.aspx" runat="server"><span>My Wall</span></a></li>
   <li id="L2" runat="server"><a id="A2" href="../ClientSide/employee/eeSettings.aspx" runat="server"><span>Setting</span></a></li>
   <li id="Li1" runat="server"><a id="A4" href="../ClientSide/employee/eeSettings.aspx" runat="server"><span>Admin</span></a>
   <ul style="width:100%">
   <li runat="server"><a href="#" runat="server"><span>bla</span></a></li>
   <li runat="server"><a href="#" runat="server"><span>bli</span></a></li>
   </ul>
   </li>
   <li id="L3" runat="server" style="position:absolute; right:1%;" ><a id="A3" href="../ClientSide/Registration/registration.aspx" runat="server"><span>Sign Up</span></a></li>
</ul>
</div>
