I was hesitant to try this plugin based on the negative review it received, but am very please I did! Unfortunately I tried a PAID plugin first, which I was not happy with as it was loading the accordian first instead of tabs. I tried reaching out to the developer and was not happy with his response...he said "maybe I you have too many tabs" What, really? I only had 3 tabs! Anyway, I decided to give this a shot. It was very basic and bare-bones for a plugin, no customization whatsoever, BUT was very easy to customize the appearance with basic HTML and CSS and now looks better than the PAID version.
Definitely give it a try, it might save you too!
Thanks for saving me on this one!
