Dear Deva,
Did you try with 'genre[]'. The brackets are needed as part of the field name.
In any case, try with this code instead:
jQuery(function( $ ) { $( "input[name='category[]']" ).click( function() { $( "input[name='category[]']" ).not(this).removeAttr('checked'); return true; } ); } );
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Caridad
