Javascript drop down section with plus minus buttons

I want to find some javascript code which will allow this:

Content A Title
------------------
------------------
Content B Title

to turn into this when you press a plus button and when you press a minus button it returns

Content A Title
------------------
Content A Here (Pictures and Text as designed html)
------------------
Content B Title
,
I have to use it 10 or so times on the screen so it needs to be able to be easily installed, short in code or shortenable by some server side or...
