So ... here is an example of how to toggle a column on and off using unordered lists:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xht...">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style type="text/css">
ul.row
{
display: block;
}
li.column1, li.column2, li.column3, li.column4, li.column5
{
display: inline;
border: 1px solid red;
padding: 0 40px 0 40px;
}
#Button1
{
margin-left: 40px;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" ></script>
<script type="text/javascript">
function toggleColumn () {
$(".column3").toggle()
};
</script>
</head>
<body>
<ul class="row">
<li class="column1">1-1</li>
<li class="column2">1-2</li>
<li class="column3">1-3</li>
<li class="column4">1-4</li>
<li class="column5">1-5</li>
</ul>
<ul class="row">
<li class="column1">2-1</li>
<li class="column2">2-2</li>
<li class="column3">2-3</li>
<li class="column4">2-4</li>
<li class="column5">2-5</li>
</ul>
<ul class="row">
<li class="column1">3-1</li>
<li class="column2">3-2</li>
<li class="column3">3-3</li>
<li class="column4">3-4</li>
<li class="column5">3-5</li>
</ul>
<input id="Button1" type="button" value="Toggle Column 3" onclick="toggleColumn()" />
</body>
</html>
Just paste this code into a file, name it test.html and open it with your favorite browser.
