Hello!
I was able to do almost exactly what I wanted by putting this recipe:

if ( $option != 'com_djclassifieds'
  or $view != 'item'
) return 206;

How ever, although the module does not display, the left is still left blank (as is an invisible module was there just holding a white space) Normally, when a module position is not used, it becomes collapsible. see here (on the left column position) :https://www.karipe.com/automotive/ad/nissan,113/2002-nissan-pathfinder-le-4wd,159.html

Can MetaMod be set such that when a module is not shown, it wont display a white space as it is doing right now?
Thanks!
