Is there a way I can make plugin work ?
As far as I can tell, the plugin is functioning fine. The accordion element that you have on that page is operating properly. Can you be more specific about what you are referring to?
Without a URL where we can see this issue, we won’t be able to be of much help. However, it sounds like your theme’s CSS styles may be interfering, or another plugin is creating a conflict. Please try it with the default WordPress Twenty-Twelve theme, which is a good generic theme to use for debugging issues like these. If the site displays fine with the default Twenty-Twelve theme active, then the problem is caused by your theme.
Hi, I don’t see our plugin active on that URL. It must be another plugin that is interfering.
