Out of the box, Joomla! does a great job of managing the content needed to make your Web site sing. But for many people, the true power of Joomla! lies in the application framework that makes it possible for developers all around the world to create powerful add-ons that are called Extensions.

Before we begin, let me explain about Joomla module.

What is a Joomla Module?

Modules in Joomla are extensions that plays as important role as a component does. Modules are like sidekicks (in super hero movie), without which a Joomla sites are incomplete. Modules are small pieces of codes that actually make the Joomla sites possible. These modules are actually seen as a Menu, Banner, Footer, Adsense codes to Login forms, newsletter subscription form, image rotator.

Elements are of utmost importance in Joomla development. Elements allows you to create custom parameter type that you can use in your metadata files.

Metadata files for your views are used configure menu links that that will use that view.

In this short tutorial, I will tell about creating elements and using it differently on different places. Elements are special files that generally adds value to parameters. For this tutorial, I will create a color element that  can be used in different components, modules, plugins where color selection is done through a color picker. I will use moorainbow as web color picker.

Also note, I am creating this element for my adsensebingo module. Hence this code has been tested and used.
