Simple Geoprocessing Widget

[tigerwoulds]

I have a geoprocessing service that executes a simple field calculation on a feature service in my map. All it does is change values in a Field called 'Visible' from 'Yes' to 'No'. There are no input or outputs the user needs to set. I just want the user to click a button to execute the service. 

Using the out of the box Geoprocessing Widget, this is as much as I can simplify it. User clicks Run and it switches to the output tab. Is there a way to hide the Output tab?

It sounds like you need to create a custom simple widget with a button
which calls a geo service on onclick.
