Fast and Simple Toggle View Content

This script is fairly straight forward. What it does is using the UL list and allow user to toggle to display the content of LI items. This is a really useful user interface feature that it helps designers to save space and build a less complicated user interface. It eliminates redundant element and allow user view the content only when they want to see it.

HTML/XHTML

<ul id="toggle-view">
	<li>
		<h3>Title 1</h3>

		<span>+</span>
		<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Morbi commodo, ipsum sed pharetra gravida, orci magna rhoncus neque, id pulvinar odio lorem non turpis. Nullam sit amet enim.</p>
	</li>
	<li>
		<h3>Title 2</h3>

		<span>+</span>
		<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Morbi commodo, ipsum sed pharetra gravida, orci magna rhoncus neque, id pulvinar odio lorem non turpis. Nullam sit amet enim.</p>
	</li>
	<li>
		<h3>Title 3</h3>

		<span>+</span>
		<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Morbi commodo, ipsum sed pharetra gravida, orci magna rhoncus neque, id pulvinar odio lorem non turpis. Nullam sit amet enim.</p>
	</li>
</ul>

CSS

The most important thing is, we have to make sure the P is hidden by default.

#toggle-view {
	list-style:none;	
	font-family:arial;
	font-size:11px;
	margin:0;
	padding:0;
	width:300px;
}

	#toggle-view li {
		margin:10px;
		border-bottom:1px solid #ccc;
		position:relative;
		cursor:pointer;
	}
	
	#toggle-view h3 {
		margin:0;
		font-size:14px;
	}

	#toggle-view span {
		position:absolute;
		right:5px; top:0;
		color:#ccc;
		font-size:13px;
	}
	
	#toggle-view p {
		margin:5px 0;
		display:none;
	}	

JS - jQuery

We attach click event to the LI item and everytime a user click on the item check if P tag is visible. If it's hidden, show it otherwise hide it. Also, it will change the html value for the SPAN to either plus or negative sign.

$(document).ready(function () {
	
	$('#toggle-view li').click(function () {

		var text = $(this).children('p');

		if (text.is(':hidden')) {
			text.slideDown('200');
			$(this).children('span').html('-');		
		} else {
			text.slideUp('200');
			$(this).children('span').html('+');		
		}
		
	});

});
