If you ever wondered how you can toggle the visibility of sub-menu items of RSJoomla! templates, here's how.
This scenario can be achieved in a couple of ways (e.g. template override for the menu module), however, this tutorial covers a way to add this functionality through CSS and Javascript (jQuery). Note that although this tutorial was created using RSJuno!, the same principle can be applied to all the templates (with some fixes). Basically, we are going to use the custom.css and custom.js files of the templates to create a button and add functionality.
Will be posted after admin approval.
