Whenever we do something new, we tend to co-relate this new thing with our prior experience. So before I go ahead with my main topic i.e. Radio Button in FPM Forms, I would give a quick re-cap on how the Radio Buttons work in SAP's hero UI - Web Dynpro ABAP. We have "Radio Buttons" UI element in Web Dynpro ABAP and we have an option to bind multiple radio buttons to the same context node(in other way we are grouping these Radio buttons) -
Main Story
Radio buttons in FPM forms works in a different way. There is no "Radio Buttons" UI control, instead you have "Radio Button Group" -
The field that is linked to "Radio Button Group" should have the possible Radio buttons / options defined at the Data element level itself.
Link the field to the Radio Button Group -
Make sure you set the "Position" and "Column Count" properties appropriately to control the display of Radio buttons -
Thanks to Sarabpreet for joining me in exploring this concept in FPM Forms.
