[Plugin: Query Multiple Taxonomies] Taxonomy Drill Down Widget

I am using the Taxonomy_Drill_Down_Widget widget to display 3 drop down lists. 1 category. 2 sports. 3 athletes

This is my code

the_widget('Taxonomy_Drill_Down_Widget', array(
    'title' => '',
    'mode' => 'dropdowns',
    'taxonomies' => array( 'category', 'sports', 'athletes' )
));

I would like to be able to set a default category to be searched and remove the category drop down list all together. This would leave just the “sports” and “athletes” drop down lists.

Anyone know how I could do this?

Thanks in advance
