joomla contents

Modules, plug-ins, and components all allow you to define configuration parameters through XML files. Many common parameter types are predefined and can be used in Joomla extensions. Every parameter you define must have five basic attributes.

1. Parameter name, so you can reference it later in your code.
2. A default value to be displayed and used if no value is chosen.
3. A visible label
4. A description appearing when the mouse cursor hovers over it
5. The type of parameter
