if i try to add another button next to Search Button in SearchBox.ascx as below. whole template messed up. It keeps the Menu at left most side and move the whole searchbox below it and then content box little right from the centre. i am not sure how can i control it? i just need to add another button next to Search Button.

<%@ Control Language="C#" AutoEventWireup="true" Inherits="NopSolutions.NopCommerce.Web.Modules.SearchBoxControl"
    CodeBehind="SearchBox.ascx.cs" %>
<ul>
    <li>
        <asp:TextBox ID="txtSearchTerms" runat="server" SkinID="SearchBoxText" Text="<% $NopResources:Search.SearchStoreTooltip %>" />&nbsp;
    </li>
    <li>
        <asp:Button runat="server" ID="btnSearch" OnClick="btnSearch_Click" Text="<% $NopResources:Search.SearchButton %>"
            CssClass="searchboxbutton" CausesValidation="false" />
