1. Introduction

Nowadays, a lot of websites are using tab based content as a way to save spaces in a webpage. I have seen a lot of wordpress websites using a tabbed interface for its category, posts, comments and random posts content. It's a good "space-saver" and if used it correctly, it can boost your website usability as well. Right, first of all, we need to have the ideas and the design structure for this tabbed interface.
Before we start, if you are looking for a web hosting company, this is a good review - Hostgator Review.
My ideas:
  • Buttons on the top, content reside in different DIV elements,
  • Click on one of the buttons, it shows the relevant content;
  • Click on other buttons, it hides the existing and display the correct one.
The Design structure:

2. HTML

In case the image above doesnt load, allow me to explain the design structure again. The UL#tabMenu is the buttons on the top a.k.a. Tabs. This is where you click, and it will trigger the jQuery to loads the content.
Inside the boxBody, you need to specify 5 DIVs, the number of DIV will depend on how many items you defined in #tabMenu, in this case, we have 5, therefre, you need 5 DIV elements defined in .boxBody.

The javascript loads the content based on the DIV's index in .boxBody. For example, if you clicked o the first button (the star or index 0), it will load the first DIV in the .boxBody (DIV index 0).
Therefore, arrangement of DIV in .boxBody must match with the arrangement of button in #tabMenu.

4. Javascript

Alright, the fun part. It took me a while to read the jQuery documentation to make it works the way I want. And yes, I made it. As usual, I have put comments on each line. I put the animate effect on category page. I have a tutorial about it - Navigation List menu + Jquery Animate Effect Tutorial

        $('.boxBody div.parent:eq(' + $('#tabMenu > li').index(this) + ')').slideDown('1500');
         
     }
  }).mouseover(function() {
 
    //Add and remove class, Personally I dont think this is the right way to do it,
    //if you have better ideas to toggle it, please comment   
    $(this).addClass('mouseover');
    $(this).removeClass('mouseout');  
     
  }).mouseout(function() {
     
    //Add and remove class
    $(this).addClass('mouseout');
    $(this).removeClass('mouseover');   
     
  });
 
   
  //Mouseover with animate Effect for Category menu list  :)
  $('.boxBody #category li').mouseover(function() {
 
    //Change background color and animate the padding
    $(this).css('backgroundColor','#888');
    $(this).children().animate({paddingLeft:"20px"}, {queue:false, duration:300});
  }).mouseout(function() {
     
    //Change background color and animate the padding
    $(this).css('backgroundColor','');
    $(this).children().animate({paddingLeft:"0"}, {queue:false, duration:300});
  }); 
     
  //Mouseover effect for Posts, Comments, Famous Posts and Random Posts menu list.
  $('.boxBody li').click(function(){
    window.location = $(this).find("a").attr("href");
  }).mouseover(function() {
    $(this).css('backgroundColor','#888');
  }).mouseout(function() {
    $(this).css('backgroundColor','');
  });  
     
});
 
</script>

5. Finally

You will get a beautiful jQuery Tabbed Side Menu!
However, in category page, if you were using IE, the LI can't be hightlighted when mouse hover it in (that's why we all hate IE). If you know what's the problem, please advise : )
Last but not least, check out the demo or download the source code to play with it. Any questions. please leave your comment :)
Support me by bookmark this article and share it to your friends : ) Thanks

Update


15-9-2011: Fixed DIV issue.
14-4-2009: Remove click event in the LI, change the display attribute in #category to block.
