回答5:

You don\'t have to always use ul elements to achieve that, you can use other elements too as seen below. Here there are 2 examples, one using div and one using select.

This examples demonstrates the basic functionality, but can be extended/enriched more. It is tested in linux only (iceweasel and chrome).

<!DOCTYPE html>
<html>
<head>
<meta charset=\'UTF-8\'>
<style>
.drop_container
{
  position:relative;
  float:left;
}
.always_visible
{
  background-color:#FAFAFA;
  color:#333333;
  font-weight:bold;
  cursor:pointer;
  border:2px silver solid;
  margin:0px;
  margin-right:5px;
  font-size:14px;
  font-family:\"Times New Roman\", Times, serif;
}
.always_visible:hover + .hidden_container
{
  display:block;
  position:absolute;
  color:green;
}
.hidden_container
{
  display:none;
  border:1px gray solid;
  left:0px;
  background-color:#FAFAFA;
  padding:5px;
  z-index:1;
}
.hidden_container:hover
{
  display:block;
  position:absolute;
}
.link
{
  color:blue;
  white-space:nowrap;
  margin:3px;
  display:block;
}
.link:hover
{
  color:white;
  background-color:blue;
}
.line_1
{
  width:800px;
  border:1px tomato solid;
  padding:5px;
}
</style>      
</head>

<body>

<div class=\"line_1\">
<div class=\"drop_container\">
  <select class=\"always_visible\" disabled><option>Select</option></select>
  <div class=\"hidden_container\">
  <a href=\"http://www.google.gr\" class=\"link\">Option_ 1</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option__ 2</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option___ 3</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option____ 4</a>
  </div>
</div>
<div class=\"drop_container\">
  <select class=\"always_visible\" disabled><option>Select</option></select>
  <div class=\"hidden_container\">
  <a href=\"http://www.google.gr\" class=\"link\">____1</a>
  <a href=\"http://www.google.gr\" class=\"link\">___2</a>
  <a href=\"http://www.google.gr\" class=\"link\">__3</a>
  <a href=\"http://www.google.gr\" class=\"link\">_4</a>
  </div>
</div>
<div style=\"clear:both;\"></div>
</div>

<br>

<div class=\"line_1\">
 <div class=\"drop_container\">
  <div class=\"always_visible\">Select___</div>
  <div class=\"hidden_container\">
  <a href=\"http://www.google.gr\" class=\"link\">Option_ 1</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option__ 2</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option___ 3</a>
  <a href=\"http://www.google.gr\" class=\"link\">Option____ 4</a>
  </div>
</div>
 <div class=\"drop_container\">
  <div class=\"always_visible\">Select___</div>
  <div class=\"hidden_container\">
  <a href=\"http://www.google.gr\" class=\"link\">Option_ 1</a>

Create simple drop-down menu using HTML and CSS

CSS:

<style>
.dropdown {
    position: relative;
    display: inline-block;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    padding: 12px 16px;
    z-index: 1;
}

.dropdown:hover .dropdown-content {
    display: block;
}
</style>

and HTML:

<div class=\"dropdown\">
  <span>Mouse over me</span>
  <div class=\"dropdown-content\">
    <p>Hello World!</p>
  </div>
</div>
