I was using another plugin for tabs but when I wanted to use accordians,it simply didn't have the functionality. I did some research and found Olevmedia Shortcodes. I downloaded this yesterday, had a play around with it today and, can I just say, this really is a top notch plugin.
I've actually deleted the other plugin I was using and switched all my tabs etc over to this.
It's pretty easy to customise though CSS too, so if you've got a child theme going the options for appearance are, more or less, endless.
