Hello Lee Chi Wai

Sorry, this feature does not exist. You can customize the code by yourself. We do not provide customization support. Please follow this documentation Tip no 7 and override the addon.

Best regards

Ok.

I've override the addon. Almost got it to work. Bootstrap helps a lot.

Thanks!

You are welcome. Glad to know this.

Please accept the answer that helped you. It will be then easier to find the solution for the other users with the same issue. There is a button to accept answer after each comment.

I have a humble request too. It would be very kind of you if you can manage some moment to give us feedback on Joomla Extension Directory. This will inspire us to improve.
