我想设计一个菜单和子菜单，如this。CSS水平导航菜单列表对齐
我试图在我已经有的菜单中进行增强，但它并不从菜单的开始处开始。我试图编辑CSS，但我无法弄清楚在哪里解决这个问题。
这是我正在尝试修复的菜单的屏幕截图。
为菜单中的HTML：
<div style="width:100%; border:1px solid black" align="center">
<ul id="nav-one" class="dropmenu" style="width:1024px; border:1px solid black;">
<li>
<a href="#">Home</a>
</li>
<li>
<a href="#">ABOUT BOST</a>
<ul>
<li><a href="#">Support</a></li>
<li><a href="#">Help</a></li>
<li><a href="#">Examples</a></li>
<li><a href="#">Your work</a></li>
</ul>
</li>

</ul>
</li>

<div class="products" align="left">
