我正在尝试设计这样的菜单和子菜单。
我试图对已有的菜单进行改进，但它不是从菜单的开头开始的。我试图编辑 CSS，但我不知道在哪里解决这个问题。
这是我要修复的菜单的屏幕截图。
菜单的 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>
