Hi,

Radio buttons in mobile is not considered a good user nterface pattern. In OutSystems you implement it with a button group.

If you have a list of options you want to let the user choose from then you can use the drop-down widget. Which I think shows by default also a radio button for each item (at least on Android)

hmm, why ?

could function button groub same like function radio button ?

 my friend talked to me, can it be outsystem make  radiobutton with css ?

and the image I give example radiobutton with icon.

yes of course you can make it yourself, it should not be that difficult.

But you should ask yourself why OutSystems or even Apple with IOS choose not to over a radio button widget?

OutSystems when creating there UI frameworks look at many mobile and web applications and implemented the most used UI patterns. 

That said, if you want it, it should not be that difficult to implement yourself. If you make a custom widget in a common UI module and assign a radio button icon to it, it will even show up in the widget bar in service studio.
