Not without doing some UI tricks (think of newer apps like Room Lighting and the newer incantations of Rule 5.1), which are a bit difficult and not "officially" a part of the UI framework.
But there are ways to allow a single selection, generally the intent of radio buttons. Typically, you would make an input
with type: enum
and, as you may guess, without multiple: true
(the default is false
, though you can specify that too if you want). You may need to re-think how text is displayed in your UI for this to make sense, as extremely long strings will typically not display well in drop-downs (e.g., perhaps consider more verbosity elsewhere, say in a paragraph
, if needed to explain what the drop-downs are).
