Views exposed taxonomy filter - show only terms within results I have a block display with an exposed 'term' filter using BEF links filter.
I have the need to reduce the terms to display only the ones that show within the blocks results.

For example I have 'term1', 'term2', 'term3' - then if within the results there is only 'term1', 'term2' - I need to remove 'term3' from the list of filter links.

I realize that the filter is built before display so I am having difficulty grasping how the filter can be modified depending on what is in the display.

Any help is much appreciated.
Have a look at views_hacks. Specifically refer to Views Selective Exposed Filters (views_filters_selective)
