questions.
When should I use radio buttons instead of a dropdown?
Use radio buttons for two to five options that people should see at a glance. Switch to a select dropdown when the list is longer.
How do I preselect an option?
Add the checked attribute to one of the generated inputs. Leave all unchecked if you want to know the person made an active choice.
