Building Tabbed Navigation using SpryTabbedPanels
The Tabbed Navigation is the latest trend while designing a Website. If it is blog then you can notice the content titled ‘Featured Content’ or ‘Latest’ arranged in tabs. If it is a Website then there are tabs on top replacing menu items. If coded correctly the tabs give a fresh outlook to your Website, save resources, and present maximum information in less area. In addition, almost every user is familiar with the tabs and their working. Tab, ALT+Tab, and Ctrl+Tab are the most pressed keys on any keyboard on this earth. Thinking to use the tabbed navigation in your Web design then we are here to help you out. Adobe Labs provide access to its SpryTabbedPanels without any cost. Here we’ll guide you how to use the SpryTabbedPanel code to create Tabbed Navigation.
An outer div contains – list of tabs, all panels, div container to have content panels, and div tag for each panel. The SpryTabbedPanels use JavaScript to toggle between the tabs. Therefore, we’ll include the JavaScript code within the HTML tag. To modularize the code, we’ll create a separate JS file and link it through script tag inside head tag. This js file will define the functions related to the Tabbed Panel. Before closing the body tag, we’ll define a script tag to use JavaScript to make Tabbed Panel interactive. We’ll also link a style sheet in the head tag.
Adobe Labs provide the SpryTabbedPanels.js to use with the HTML code. You can scroll down to bottom to download the source files used in this article. Before that, we’ll illustrate the code of HTML and CSS files in this article. We recommend you not to change the file name of js and css files. However, you can modify the code as per your convenience.
In our case, we’ve located JS, CSS and HTML files in the same folder. Please modify the path in code if you’re placing the CSS and JS files in other location.

<!--Link the Spry TabbedPanels CSS-->
<link href="SpryTabbedPanels.css" rel="swift/stylesheet" type="text/css" />
<!--Link the Spry TabbedPanels JavaScript library-->
<script src="SpryTabbedPanels.js" type="swift/javascript"></script>
</head>
<body>
<!--Create the Tabbed Panel widget and assign classes to each element-->
<div class="TabbedPanels" id="TabbedPanels1">
<ul class="TabbedPanelsTabGroup">
<li class="TabbedPanelsTab">Tab 1</li>
<li class="TabbedPanelsTab">Tab 2</li>
<li class="TabbedPanelsTab">Tab 3</li>
<li class="TabbedPanelsTab">Tab 4</li>
</ul>
<div class="TabbedPanelsContentGroup">
<div class="TabbedPanelsContent">Tab 1 Content</div>
<div class="TabbedPanelsContent">Tab 2 Content</div>
<div class="TabbedPanelsContent">Tab 3 Content</div>
<div class="TabbedPanelsContent">Tab 4 Content</div>
</div>
</div>
<!--Initialize the Tabbed Panel widget object-->
<script type="swift/javascript">
var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1");
</script>
</body>
Categorizing the HTML code
- Link the SpryTabbedPanels.js and SpryTabbedPanels.css file within the HTML code.
<!--Link the CSS style sheet that styles the tabbed panel--> <link href="SpryTabbedPanels.css" rel="stylesheet" type="text/css" /> <!--Link the Spry TabbedPanels JavaScript library--> <script src="SpryTabbedPanels.js" type="swift/javascript"></script>
- Add following code to create the SpryTabbedPanel.
<div class="TabbedPanels" id="TabbedPanels1"> </div>
- Mention an ul class TabbedPanelsTab Group to create the tab inside above div.
<div class="TabbedPanels" id="TabbedPanels1"> <ul class="TabbedPanelsTabGroup"> <li class="TabbedPanelsTab">Tab 1</li> <li class="TabbedPanelsTab">Tab 2</li> <li class="TabbedPanelsTab">Tab 3</li> <li class="TabbedPanelsTab">Tab 4</li> </ul> </div>
- Add a div ‘TabbedPanelsContentGroup, after the ul class to create a container for including the contents of each tab.
<div class="TabbedPanels" id="TabbedPanels1"> <ul class="TabbedPanelsTabGroup"> <li class="TabbedPanelsTab">Tab 1</li> <li class="TabbedPanelsTab">Tab 2</li> <li class="TabbedPanelsTab">Tab 3</li> <li class="TabbedPanelsTab">Tab 4</li> </ul> <div class="TabbedPanelsContentGroup"> </div> </div>
- In TabbedPanelsContentGroup, include one div tag with class (TabbedPanelsContent) for each tab to have its content.
<div class="TabbedPanels" id="TabbedPanels1"> <ul class="TabbedPanelsTabGroup"> <li class="TabbedPanelsTab">Tab 1</li> <li class="TabbedPanelsTab">Tab 2</li> <li class="TabbedPanelsTab">Tab 3</li> <li class="TabbedPanelsTab">Tab 4</li> </ul> <div class="TabbedPanelsContentGroup"> <div class="TabbedPanelsContent">Tab 1 Content</div> <div class="TabbedPanelsContent">Tab 2 Content</div> <div class="TabbedPanelsContent">Tab 3 Content</div> <div class="TabbedPanelsContent">Tab 4 Content</div> </div> </div>
- Include following code to initialize the SpryTabbedPanels object. Here, new operator will initialize the Tabbed Panels and transforms the div content with TabbedPanels1 ID into an interactive tabbed object.
<script type="swift/javascript"> var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1"); </script>
What you can do more?
- If you want to add more tab then add a li class in TabbedPanelsTabGroup and a div class in TabbedPanelsContentGroup. To remove a tab, you’ve to delete the li class and its relevant div class from both groups.
- You can change the div class ‘TabbedPanels’ to ‘VTabbedPanels’ if you want to include the vertical tabs in your Web design.
<div class="VTabbedPanels" id="TabbedPanels1"> <ul class="TabbedPanelsTabGroup"> <li class="TabbedPanelsTab">Tab 1</li> <li class="TabbedPanelsTab">Tab 2</li> <li class="TabbedPanelsTab">Tab 3</li> <li class="TabbedPanelsTab">Tab 4</li> </ul> <div class="TabbedPanelsContentGroup"> <div class="TabbedPanelsContent">Tab 1 Content</div> <div class="TabbedPanelsContent">Tab 2 Content</div> <div class="TabbedPanelsContent">Tab 3 Content</div> <div class="TabbedPanelsContent">Tab 4 Content</div> </div> </div>
- Make use of tabIndex in li class ‘TabbedPanelsTab’ to enable keyboard navigation.
<li class="TabbedPanelsTab" tabIndex="0">Tab 1</li> <li class="TabbedPanelsTab" tabIndex="1">Tab 2</li> <li class="TabbedPanelsTab" tabIndex="2">Tab 3</li>
