The Joomla Accordion module creates a accordion view from joomla articles within a category.

Just select the category and the module does the rest.

The frontend output is completely responsive, provided your template is also responsive, the accordion will be displayed optimally on every output device. In the backend, you have options to adjust the module to your needs, like setting the open effect, or if the accordion should allow multiple open.

The design of the module can be changed via CSS, the output has been separated from the design, which allows to style the module with a minimum of time.
