I am using Drupal 7 and Views 7.x-3.7.
In a view I have an exposed filter "gender".
If I select the filter type as 'single', it works fine. But I want radio buttons rather than dropdown so I select 'grouped filter' option.
Then the filter renders as I like.
But it always returns an empty result set.
There must be a setting that I am missing. Can you please point me to it?
