@kevspadilla: I got an error when I clicked a second time on the same tab:

Hi! @jspdown ,
Error message doesn't show in mine. It seems there's an error regarding this line of code.

// Add animation to the accordion group content element.children().last().slideToggle(); 

Please see this fiddle...
