Taxonomy exposed filter I am working with Drupal 7.
How do I limit a taxonomy drop-down exposed filter to only display the terms used by nodes in view results?

I understand that the list is populated before the views takes place, but this means that I am often left with tags that display nothing ( since they are hidden with my view).
Views Hacks does this with Views Selective Exposed Filters:


  Views Selective Exposed Filters
  
  On list and checkbox exposed filters, you can specify the filter
  option "Limit list to result set" to only display values that are
  actually returned in the view's results. The filter option "Further
  limit list to active filters" restricts the displayed values to view
  results obtained by applying exposed filter values.
