I had almost given up hope when I found this. It is so simple to work with yet so powerful.
Because you can create your own module and place it in the accordion you can do pretty much anything you like. Plus the code is very simple to understand so I have successfully modified it to suit my exact needs.
I am surprised I am the first person to comment on this excellent extension.
Installation was easy and although I had a few queries configuring the support was excellent so I had no problems getting things up and running promptly and efficiently.
I agree with the other reviewers that installation was easy and it worked right away on a desktop browser.
Unfortunately where this all fell apart was when I reported an issue. I found that in my template (from Joomlart who I have used often with no issues) the links did not work in an ipad/iphone, despite this being one of the key advertized features on the website. I reported this using the ticket system and have had to chase constantly with no success.
In addition, I asked if it would be possible for some customization (to be able to color the tabs independently rather than all the same color). This, I was told, was possible for a fee which I paid (along with the full price for the extension itself). I was given a date and nothing appeared. When I asked I was given an apology and a new date. This was not met. Now I can't get a response at all.
So in summary, download the free one and if it works, good for you but if it doesn't don't expect a resolution.
I am now looking for an alternative, including a bespoke development.
