<p>When an <code>AutoCompleteExtender</code> is displayed in IE6 it seems to ignore z-index and renders below any select controls (like <strong>dropdownlists</strong>) in IE6.</p>

<pre><code>&lt;asp:TextBox ID="TextBox1" runat="server"  /&gt;
&lt;cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" 
    TargetControlID="TextBox1" EnableCaching="true" CompletionSetCount="5" 
    FirstRowSelected="true" ServicePath="~/Services/Service1.asmx" ServiceMethod="GetSuggestion" /&gt;
&lt;asp:DropDownList ID="DropDownList1" runat="server"&gt;
    &lt;asp:ListItem Text="Item 1" Value="0" /&gt;
    &lt;asp:ListItem Text="Item 2" Value="1" /&gt;
&lt;/asp:DropDownList&gt;
</code></pre>

<p>How do I make it render above <strong>dropdownlists</strong>?</p>
