I'm trying to emulate a technique I've seen on many web sites, but I'm a bit lost.  I would like to have a series of horizontal tabs that load content in a div.  Once the content is loaded the user would have the option to select a "read more" button and the rest of the content would appear.   At that point they would have a button labeled "collapse" to return to the original state. 

I read on a forum that there are many ways to do this, but there might be an easy way to do it using jQuery. 
I've attached a link to the behavior I am trying to recreate.
