Today we are going to create a fancy sliding form that shows some validation feedback to the user after each step. This form saves a lot of space and is easy to access – it basically works like a slide show, just that we have fieldsets of a form instead of images.

So let’s start!

The Markup

The HTML will consist of a wrapper container where we will place a form with fieldsets. Each fieldset will be a step in our sliding form:

<h1>Fancy Sliding Form with jQuery</h1>
<div id="wrapper">
	<div id="steps">
		<form id="formElem" name="formElem" action="" method="post">
			<fieldset class="step">
				<legend>Account</legend>
				<p>
					<label for="username">User name</label>
					<input id="username" name="username" />
				</p>
				<p>
					<label for="email">Email</label>
					<input id="email" name="email" type="email" />
				</p>
				<p>
					<label for="password">Password</label>
					<input id="password" name="password" type="password" />
				</p>
			</fieldset>
			<fieldset>
			...
			</fieldset>
		</form>
	</div>
	<div id="navigation" style="display:none;">
		<ul>
			<li class="selected">
				<a href="#">Account</a>
			</li>
			<li>
				<a href="#">Personal Details</a>
			</li>
			<li>
				<a href="#">Payment</a>
			</li>
			<li>
				<a href="#">Settings</a>
			</li>
			<li>
				<a href="#">Confirm</a>
			</li>
		</ul>
	</div>
</div>

The navigation with all the links to the steps will be an unordered list that is initially hidden. We will show it in our JavaScript function.
Let’s look at the style.

The CSS

The main wrapper and the steps container will have the following style:

#wrapper{
    -moz-box-shadow:0px 0px 3px #aaa;
    -webkit-box-shadow:0px 0px 3px #aaa;
    box-shadow:0px 0px 3px #aaa;
    -moz-border-radius:10px;
    -webkit-border-radius:10px;
    border-radius:10px;
    border:2px solid #fff;
    background-color:#f9f9f9;
    width:600px;
    overflow:hidden;
}
#steps{
    width:600px;
    overflow:hidden;
}
.step{
    float:left;
    width:600px;
}

The class step will be given to each fieldset. Let’s style the navigation:

#navigation{
    height:45px;
    background-color:#e9e9e9;
    border-top:1px solid #fff;
    -moz-border-radius:0px 0px 10px 10px;
    -webkit-border-bottom-left-radius:10px;
    -webkit-border-bottom-right-radius:10px;
    border-bottom-left-radius:10px;
    border-bottom-right-radius:10px;
}
#navigation ul{
    list-style:none;
	float:left;
	margin-left:22px;
}
#navigation ul li{
	float:left;
    border-right:1px solid #ccc;
    border-left:1px solid #ccc;
    position:relative;
	margin:0px 2px;
}

The single link elements will have a neat CSS3 gradient as background:

#navigation ul li a{
    display:block;
    height:45px;
    background-color:#444;
    color:#777;
    outline:none;
    font-weight:bold;
    text-decoration:none;
    line-height:45px;
    padding:0px 20px;
    border-right:1px solid #fff;
    border-left:1px solid #fff;
    background:#f0f0f0;
    background:
        -webkit-gradient(
        linear,
        left bottom,
        left top,
        color-stop(0.09, rgb(240,240,240)),
        color-stop(0.55, rgb(227,227,227)),
        color-stop(0.78, rgb(240,240,240))
        );
    background:
        -moz-linear-gradient(
        center bottom,
        rgb(240,240,240) 9%,
        rgb(227,227,227) 55%,
        rgb(240,240,240) 78%
        )
}
#navigation ul li a:hover,
#navigation ul li.selected a{
    background:#d8d8d8;
    color:#666;
    text-shadow:1px 1px 1px #fff;
}

When a step get’s validated, we will either add a span indicating that everything is fine, or a span that shows that something is wrong in the form step:

span.checked{
    background:transparent url(../images/checked.png) no-repeat top left;
    position:absolute;
    top:0px;
    left:1px;
    width:20px;
    height:20px;
}
span.error{
    background:transparent url(../images/error.png) no-repeat top left;
    position:absolute;
    top:0px;
    left:1px;
    width:20px;
    height:20px;
}

The styles for the form elements look as follows:

#steps form fieldset{
    border:none;
    padding-bottom:20px;
}
#steps form legend{
    text-align:left;
    background-color:#f0f0f0;
    color:#666;
    font-size:24px;
    text-shadow:1px 1px 1px #fff;
    font-weight:bold;
    float:left;
    width:590px;
    padding:5px 0px 5px 10px;
    margin:10px 0px;
    border-bottom:1px solid #fff;
    border-top:1px solid #d9d9d9;
}
#steps form p{
    float:left;
    clear:both;
    margin:5px 0px;
    background-color:#f4f4f4;
    border:1px solid #fff;
    width:400px;
    padding:10px;
    margin-left:100px;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius: 5px;
    -moz-box-shadow:0px 0px 3px #aaa;
    -webkit-box-shadow:0px 0px 3px #aaa;
    box-shadow:0px 0px 3px #aaa;
}
#steps form p label{
    width:160px;
    float:left;
    text-align:right;
    margin-right:15px;
    line-height:26px;
    color:#666;
    text-shadow:1px 1px 1px #fff;
    font-weight:bold;
}
#steps form input:not([type=radio]),
#steps form textarea,
#steps form select{
    background: #ffffff;
    border: 1px solid #ddd;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;
    border-radius: 3px;
    outline: none;
    padding: 5px;
    width: 200px;
    float:left;
}
#steps form input:focus{
    -moz-box-shadow:0px 0px 3px #aaa;
    -webkit-box-shadow:0px 0px 3px #aaa;
    box-shadow:0px 0px 3px #aaa;
    background-color:#FFFEEF;
}
#steps form p.submit{
    background:none;
    border:none;
    -moz-box-shadow:none;
    -webkit-box-shadow:none;
    box-shadow:none;
}
#steps form button {
	border:none;
	outline:none;
    -moz-border-radius: 10px;
    -webkit-border-radius: 10px;
    border-radius: 10px;
    color: #ffffff;
    display: block;
    cursor:pointer;
    margin: 0px auto;
    clear:both;
    padding: 7px 25px;
    text-shadow: 0 1px 1px #777;
    font-weight:bold;
    font-family:"Century Gothic", Helvetica, sans-serif;
    font-size:22px;
    -moz-box-shadow:0px 0px 3px #aaa;
    -webkit-box-shadow:0px 0px 3px #aaa;
    box-shadow:0px 0px 3px #aaa;
    background:#4797ED;
}
#steps form button:hover {
    background:#d8d8d8;
    color:#666;
    text-shadow:1px 1px 1px #fff;
}

And now, let’s add some JavaScript magic!

The JavaScript

In our function we will first take care of the display of the slider. For that we need to calculate the width of the elements inside. We will also take care of the sliding when we tab through the inputs. When the user hits tab when he is in the last input of a fieldset, we make the next fieldset slide into place and focus on the first field.

The validation of the form is based on all inputs being required fields. If we slide to the next fieldset and did not fill out all the inputs of the previous one, we will mark the missing inputs with a red background and add our little error span to the navigation item. If everything was fine, we will add the span with the check mark so that the user knows, the step was correct. We will not allow the user to submit the form if one of the steps contains errors.

$(function() {
	/*
	number of fieldsets
	*/
	var fieldsetCount = $('#formElem').children().length;

	/*
	current position of fieldset / navigation link
	*/
	var current 	= 1;

	/*
	sum and save the widths of each one of the fieldsets
	set the final sum as the total width of the steps element
	*/
	var stepsWidth	= 0;
    var widths 		= new Array();
	$('#steps .step').each(function(i){
        var $step 		= $(this);
		widths[i]  		= stepsWidth;
        stepsWidth	 	+= $step.width();
    });
	$('#steps').width(stepsWidth);

	/*
	to avoid problems in IE, focus the first input of the form
	*/
	$('#formElem').children(':first').find(':input:first').focus();	

	/*
	show the navigation bar
	*/
	$('#navigation').show();

	/*
	when clicking on a navigation link
	the form slides to the corresponding fieldset
	*/
    $('#navigation a').bind('click',function(e){
		var $this	= $(this);
		var prev	= current;
		$this.closest('ul').find('li').removeClass('selected');
        $this.parent().addClass('selected');
		/*
		we store the position of the link
		in the current variable
		*/
		current = $this.parent().index() + 1;
		/*
		animate / slide to the next or to the corresponding
		fieldset. The order of the links in the navigation
		is the order of the fieldsets.
		Also, after sliding, we trigger the focus on the first
		input element of the new fieldset
		If we clicked on the last link (confirmation), then we validate
		all the fieldsets, otherwise we validate the previous one
		before the form slided
		*/
        $('#steps').stop().animate({
            marginLeft: '-' + widths[current-1] + 'px'
        },500,function(){
			if(current == fieldsetCount)
				validateSteps();
			else
				validateStep(prev);
			$('#formElem').children(':nth-child('+ parseInt(current) +')').find(':input:first').focus();
		});
        e.preventDefault();
    });

	/*
	clicking on the tab (on the last input of each fieldset), makes the form
	slide to the next step
	*/
	$('#formElem > fieldset').each(function(){
		var $fieldset = $(this);
		$fieldset.children(':last').find(':input').keydown(function(e){
			if (e.which == 9){
				$('#navigation li:nth-child(' + (parseInt(current)+1) + ') a').click();
				/* force the blur for validation */
				$(this).blur();
				e.preventDefault();
			}
		});
	});

	/*
	validates errors on all the fieldsets
	records if the form has errors in $('#formElem').data()
	*/
	function validateSteps(){
		var FormErrors = false;
		for(var i = 1; i < fieldsetCount; ++i){
			var error = validateStep(i);
			if(error == -1)
				FormErrors = true;
		}
		$('#formElem').data('errors',FormErrors);
	}

	/*
	validates one fieldset
	and returns -1 if errors found, or 1 if not
	*/
	function validateStep(step){
		if(step == fieldsetCount) return;

		var error = 1;
		var hasError = false;
		$('#formElem').children(':nth-child('+ parseInt(step) +')').find(':input:not(button)').each(function(){
			var $this 		= $(this);
			var valueLength = jQuery.trim($this.val()).length;

			if(valueLength == ''){
				hasError = true;
				$this.css('background-color','#FFEDEF');
			}
			else
				$this.css('background-color','#FFFFFF');
		});
		var $link = $('#navigation li:nth-child(' + parseInt(step) + ') a');
		$link.parent().find('.error,.checked').remove();

		var valclass = 'checked';
		if(hasError){
			error = -1;
			valclass = 'error';
		}
		$('<span class="'+valclass+'"></span>').insertAfter($link);

		return error;
	}

	/*
	if there are errors don't allow the user to submit
	*/
	$('#registerButton').bind('click',function(){
		if($('#formElem').data('errors')){
			alert('Please correct the errors in the Form');
			return false;
		}
	});
});

And that’s it! I hope you liked the sliding form idea!

    Actually, I was thinking it might be possible to use http://api.jquery.com/focusin/ to make sure the focus is going to an element on the active tab, if not putting focus on maybe the first element on the current tab, but that might be a weird user experience and could require giving each tabbable element a class that specifies what tab it is on.

    Hello, I have integrated this form and I put a submit/save in every content of the tab. When I submit/save than it doesnt stay in the content/tab it goes back to the first. How can i fix it?

    Great form slider! It has helped in reduce my long form into easy steps. One question: Has anyone figured out how to change the height of the container based on the height of the current fieldset? I have been trying to implement this, but have had no success yet. Thanks for any assistance!

    Hello
    Very nice script
    Just a question, for tab, don’t understand the way that identify last field. Morehover what mean the $fieldset.children(‘:last’).find(‘:input’).keydown(function(e){
    if (e.which == 9)
    e.which == 9 ? its the count of field? i have put 2 more input on my tab and the autoslide system lauch before my two last fields (one input one textarea) anyway to define id of input that is the last ?
    Thanks

    For anyone interested in the IE7 problem, if you look at it you will notice that IE7 is putting more white space (first and last slide) around the area. This is the problem, it is causing the float:left of the fieldset piece to wrap around. A quick fix that will work (I’ve tested it) is adding the class “.confirm” to your last fieldset. Then add into the styles…

    #steps form fieldset.confirm{*margin:0 -20px;*float:right;}

    If you feel the * IE hack is no good, then make an IE7 only stylesheet, either way, by floating this right and using the negative margin, the problem will be taken care of.

    (or my friend’s suggestion, user a browser sniffer that tells them they need a “real browser” and cant use your site until then)

    Hey ,

    Great plugin ,i have just a small problem that i`m trying to deal with for the past 3 days,i`m trying to incorporate live validation plugin ,all works great but the validation is made per total not field by field .So i made a validation for email and username on the first field and name on the second if i enter the corect username and email it shows like is incorect only after i enter the name on the second field all other fields validate.So if i have a form with 6 field i have to get to the last one to show the user that all is completed ok.

    I know that the problem is somewhere here :
    var $this = $(this);

    var areAllValid = LiveValidation.massValidate([ email1,username,name ]);

    if(areAllValid == false ){
    …..
    Here is the website where is live in how it is now:

    My navigation doesn’t seem to work on when I put this on my site’s registration form. What another tabbed is clicked on; any fields not filled out will turn red, but that would be the only response. What am I doing wrong? By the way, this form can be found at http://www.luvbid.com/register.php

    For some reason the menu is being displayed vertically at the bottom instead of horizontally…how can I fix this?

    Thanks for posting this, Mary Lou, it is just what I’ve been looking for!

    I hope you are still answering questions about this…

    I added several fields to one tab, but it causes the height of all the tabs to to increase. How can we make each tab height to be dynamic based on content?
