[support] Display view's Exposed Filters with Term Reference Field as select list. (drupal 7).

Hi, I am using drupal 7, and views 2. I created a content type one of whose field is a term reference. In of my views i would like to use this field as a exposed filter. But I am unable to switch it to a select list option. It always defaults to the textfield. Has someone tried to do something similar, is there a way around this? Thanks, Praveen
