由于框架集，不显示子菜单

Question

我在项目中遇到一个问题，我想显示菜单和子菜单。但是由于框架集中设置的行，子菜单没有显示。 所以你帮助我做了什么改变，以便marque.html在后台运行，子菜单和子菜单的＆gt;菜单显示正确。

以下是代码段：

ul#css3menu1, ul#css3menu1 ul {
  margin: 0;
  list-style: none;
  padding: 0;
  background-color: #dedede;
  border-width: 1px;
  border-style: solid;
  border-color: #5f5f5f;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
  border-radius: 5px;
}

ul#css3menu1 ul {
  display: none;
  position: absolute;
  left: 0;
  top: 100%;
  -moz-box-shadow: 3.5px 3.5px 5px #000000;
  -webkit-box-shadow: 3.5px 3.5px 5px #000000;
  box-shadow: 3.5px 3.5px 5px #000000;
  background-color: #0000ff;
  border-radius: 6px;
  -moz-border-radius: 6px;
  -webkit-border-radius: 6px;
  border-color: #d4d4d4;
  padding: 0 10px 10px;
}

ul#css3menu1 li:hover > * {
  display: block;
}

ul#css3menu1 li {
  position: relative;
  display: block;
  white-space: nowrap;
  font-size: 0;
  float: left;
}

ul#css3menu1 li:hover {
