You can easily hide them by adding a css-command:
.rf-edt-flt-c { display:none; }
Also the input boxes will be removed when you remove the filter
/filterattribute
- attributes
A third way is to remove them via javascript using extended data tables onready
-attribute
onready="$('.rf-edt-flt-c', this).each(
function(n){
this.parentNode.removeChild(this);
});"
Hope it helps...
