An element representing an existing filter can be dragged and dropped into a canvas area. In response to the detection of the dropping of the filter, an input control can be automatically created. The selection of an input control may be based on the type (or dimension) of the filter. Alternatively, an option to create an input control can be presented to the user, wherein only valid input control types for the type of the filter are presented. If a data type of a filter changes such that the type of a corresponding input control is no longer valid, the input control may automatically be modified to a type that is valid for the new data type of the filter.
