Toggle post like in Mandigo theme
 

Trying to add a toggle post function as in the Mandigo theme. Looking att my source code on the blogg and i cant figure out how to call the div class (tags and stuff). This is the code i have to change:

jQuery('td#middle-'+ id +'div.post').animate({ height: 'toggle', opacity: 'toggle' }, 1000);

and: 'td#middle-'+ id +'div.post' is not correct

If someone can help me i can write a tutorial on this and some other changes i made to the excellent Atahualpa theme.
