anyone suggest a good plugin for…

I want to show a lot of content on one post. I came across a plugin sometime ago that gave you a ‘click for more info’ bar/tab of some sort. but without leaving the post, you could just click to open and click again to close, then go to the next one….

so you understand what im doing its a gig listing post for each bar, some have a band every night though! so by the time you write about the band, add a youtube clip and some sample tracks….post will be HUGE!!!

anyone know this plugin or recommend a plugin (or even a better way of doing this???)

thanks
Nick
