Introducing Relax Accordion: Accordion with drag-and-drop and callback functionality

I’m happy to release a jQuery plugin: Relax accordion. Relax accordion was made using jQuery and some jQuery ui components, the sortable library and the droppable library.

This plugin lives on github.

Setup

You’ll need to clone this repository to use the files here.

git clone git@github.com:alabid/relaxaccordion.git

on your unix/linux command line.

To use relax accordion, you need three core js files:

  • jQuery.js — the new wave JavaScript library. The other two .js files depend on this.
  • relax.js — JavaScript file containing the implementation of the relax accordion.
  • jQuery.draggable.droppable.custom.min.js — it contains the draggable and droppable jquery ui libraries.

If you are going to use any more of the jQuery ui libraries, I’d advise that you just download and include the jQuery ui libraries you’d use with your application together with relax.js. If you do that then you wouldn’t have to include (iii) anymore. But make sure that you have the draggable, droppable, and sortable jquery ui libraries coupled with your downloads.

Download jquery ui libraries here.

After downloading (i), (ii), (iii), you can include these files in your html file like this (and preferably in this order):

 <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="jquery.draggable.droppable.custom.min.js" 

<script type=”text/javascript” src=”relax.js”></script>
<script type=”text/javascript” src=”myscript.js”

Then you can call the relax plugin in your own script like this:

$("ul.menu").relax();

The selector ul.menu specifies the list where the relax function will act upon and make a RELAX accordion.

Usage

The .relax() function takes in an object that you could use to specify some options for the relax accordion:

 // default values $("ul.menu") .relax({ "animate" : "fast", "activate-links" : false, // or "deactivate-links" : true "openondrag" : false, ondrop: function() {}, // or null opacity: 0.7 }); 

animate option specifies how fast the accordion menus should slide up or slide down. Available options: “fast”, “slow”, “normal”.

activate-links option applies to only accordion that use <a> tags in them (which is most accordions). It deactivates all the links. You can activate the links again by simply setting this option to true.

openondrag specifies if a sublist in the relax accordion menu should be open when a drag operation is being performed. If openondrag == false, then whenever you start to drag an <li> from one container to another, any open sublist closes.

ondrop is a callback that will be called whenever an <li> is moved from one sublist to another.

For example:

ondrop: function(dropped, into, contained) { log("I am "); log(dropped); log("dropped into "); log(into); log("in this menu: "); log(contained); } 

dropped is the last list item (<li>) that was dropped before the ondrop callback was called.

into is the list <ul> into which dropped was dropped into.

contained is the container/menu that encapsulates both dropped and into.

Examples


Examples of usage of relax.js are at http://vidmuster.com. Check out these ones:

  1. Two sortable accordion menus. One uses <a> elements and the other uses <p> elements in the accordion tabs. Example 1.
  2. Two sortable accordion menus that communicate with each other. You can drag from one menu to the other and also specify callbacks that will execute just immediately after you’re done moving an <li>Example 2.

Feedback, Bugs, Suggestions

I’d really like your feedback, comments, and bug reports sent to me somehow preferably by filing an issue (github feature).
