Using jQueryUI Accordion to create a vertical menu

Introduction

A majority of web applications need a navigation menu and there are a lot plug-ins out the to create a great menu. In my case I had to create a vertical navigation menu with some expanding and collapsing behavior.  

There are a lot of solutions for creating such a menu. I was already using  jQueryUI and decided to use the Accordion for this purpose. This is what happened… Let's say that we have a simple site where we have home, projects, and About me pages and we need to create a vertical navigation menu for it using jQueryUI. 

Using the code  

The first step was to create an Accordion with the navigation links:

<div id="navigationMenu"> 
    <h3> <a href="#"> Home </a> </h3>
    <div> </div>
    <h3><a href="#"> Projects</a></h3> 
    <div> 
       <ul> 
          <li> <a href="#1"> Project 1</a> </li>
          <li> <a href="#2"> Project 2 </a> </li>
          <li> <a href="#3"> Project 3 </a> </li>
       </ul>
    </div>
    <h3> <a href="#"> About me</a></h3>
    <div></div>
</div>

We have to initialize the navigationMenu as an Accordion:

$(function () {
   //initializing the accordion
   $('#navigationMenu').accordion({
        collapsible: true,
        navigation: true,
        clearStyle: true
    });
});

OK, now we can add some code for customizing the navigation accordion. Let's decorate the menu headers and divs that don’t need to be collapsible and single with a class="single-menu-item" for headers and class="single-menu-container" for the divs:

<div id="navigationMenu"> 
  <h3 class="single-menu-item"> <a href="#"> Home </a> </h3>
  <div class="single-menu-container"> </div>
  <h3><a href="#"> Projects</a></h3> 
  <div> 
      <ul> 
          <li> <a href="#1"> Project 1</a> </li>
          <li> <a href="#2"> Project 2 </a> </li>
          <li> <a href="#3"> Project 3 </a> </li>
     </ul>
 </div>
 <h3 class="single-menu-item"> <a href="#"> About me</a></h3>
 <div class="single-menu-container"></div>
</div>

We unbind the click event from the single-menu element:

$(function () {
    //initializing the accordion
     ...
 
     $('.single-menu-item').unbind('click');
});

And as a last step we have to create some CSS rules for single-menu-item and single-menu-container that will rewrite the standard behavior of the jQuery accordion:  

#navigationMenu{ width: 270px; }
  .single-menu-item .ui-icon {display: none !important;}
  .single-menu-container {display: none !important;}

This was the last step. 

Now we have a vertical navigation menu! You can find the code of this example here.
