SQ01 - Include a check box on ABAP query Selection screen

Hi Experts,

For my Abap Query, on the selection screen i am planning to include a check box such that if i click on the check box then a field will be displayed in the resulting output . On the other hand if i do not check on i should not be able the field in the output.

Please tell me how do i do this.
