How do I turn a select list into a radio button? I have a list text field that I want to display as a series of radio buttons instead of a select (dropdown) list.  In Drupal 7, I could change this on Manage fields.  How can I do that in Drupal 8?
step 1 : choose the field type is  "list(text)".

step 2 : change the "Allowed number of values" as limited in Field settings

step 3 : change the "field widget" as Check boxes/radio buttons in Manage form display
